Product Updates

SC Navigator 24.12.1Date October 11, 2024 New Features A new attribute has been created on the Customer Product Data sheet: ‘Minimum Lead Time Adherence’. This attribute determines what percentage of demand for a given customer, location, product, period combination must be fulfilled within the lead time. When you want the model to take this into account, you have to Relax Lead Time on the Control Panel page. Improvements The custom objectives of type “Risk” are no longer shown on the control panel page. There would never be data for those custom objectives, so keeping it there could lead to potential confusion. The Risk Analysis page is now initialized after a Risk Analysis is loaded. We received some feedback based on the changes implemented in SC Navigator 24.11.1, so we made some minor changes to the behavior of the “Filter by Node Type”: If you (un)select one of the four standard elements (Customer, Supplier, Warehouse, Production), it will (un)select all the groups of the type. This will now also happen if you have elements that do not belong to a subgroup. Elements that don’t belong to any group, can be shown by unchecking every subgroup, while keeping the related standard element checked. Groups for which only part of the locations are shown, will now have a gray background in the checkbox and a tooltip to indicate that only some of the related locations are shown. The full behavior is described in Node Filters. Bug Fixes After loading an Excel template (without saving it as a dataset), the widgets on page Data - Customer did not all update correctly when making demand adjustments. Now, the Selected Demand widget refreshes after each Adjust Demand iteration and the table Demand Adjustment updates correctly as well. For Risk Analysis, Profit Decrease is now the same as Cost Increase in case there is no revenue. Previously in this case the Profit Decrease was opposite to the Cost Increase. The attribute ‘Open As Group’ was not included in the template. Curly bracket support for ‘Mode of Transport’ was not working correctly for Custom Cost attributes. Curly bracket support for ‘To Location’ in Stepwise Transport Cost was not working correctly. When not applying variable cost for a warehouse that is at the same location as a production facility, users could get an error message after optimization: “A problem occurred during the optimization. (…)” Previously, when reading input from an Excel file, an empty cell in the first column of a sheet was not properly handled. SC Navigator would not give an error message, while it stopped reading the sheet. In this new version, it will give an error message, indicating that an empty cell was found. On page Data, in the Data Dashboard widget, Suppliers and Supplier groups were not counted correctly. The geocoding did not work correctly if you specified a Postal Code and Country, but not a country-code. In that case, the model was using a special postal-code setup, while that required a country code. This resulted in inaccurate results; in some cases the returned locations were even outside the requested country. The file “_dataset_info.parquet”, created as part of a results dataset, still contained capitals and spaces in the header names. In newly generated results, these headers will now only use lower case and underscores in the names. Some exported parquet files contained columns starting with “unit_of_” that were not expected. These columns will no longer be generated in exported results. In some cases with minimum production, the model could be incorrectly marked as infeasible or display the message “A problem occurred during the optimization.”

SC Navigator 24.10.1Date August 20, 2024 New Features A new attribute has been added to the Supplier, Supplier Product, Warehouse, Warehouse Product and Production sheets: Open As Group. This attribute allows you, in multi-period models, to indicate that the entity needs to be open or closed for the complete period. There are two benefits compared to how it could be done previously: It it easier to specify and it leads to faster performance. Improvements The documentation has been restructured for easier navigation. Data Validation will raise an error when the input data includes demand for a product that has no available supply, production, or opening inventory. For some of the rate card data validations, the maximum number of detailed data validation messages has been set to 10000 in order to limit time spent on data validation. In the Node Type filters, all customer groups are now by default colored with color “Customer Default”. The color of the groups can still be changed on the ‘Customize Nodes’ dialog page that you can open from the Map widget action ‘Customize Nodes’. Bug Fixes On page Results - End to End, the direct transport lanes (from supplier to customer) were not visible on the map. When running the infeasibility analysis for a model with multi-step suppliers that do not have capacities specified, the warning message “A problem occurred during the optimization” could appear. When running the infeasibility analysis for a model with customers that have attribute Maximum # of Source Locations set, the message “No solution found - The model is still infeasible” could appear. Now, this constraint is also handled properly in the Infeasibility Analysis. For curly production group data, previously the app raised a data validation warning if any step in the individual productions had missing availability data. However, it should only need the availability data for the first step. In some rare situations, a dataset saved with the previous version of SC Navigator, could no longer be loaded. This has been fixed in this new version of SC Navigator, but it requires you to save the dataset again, from the template. With this release a new version of Inventory Planning is released as well. In the Inventory Planning app, when exporting a scenario, the Work in Progress data is now saved to the data lake as well.

SC Navigator 24.9.1Date July 30, 2024 New Features If the model has Data Separation and the user is connected to multiple business units/groups, SC Navigator will now show a new item (Business Unit) on the status bar. Users can switch between their different groups using this item. Improvements We have improved the loading of results, for results saved in this version. The results of the selected CoG Trade-Off Analysis runs can now be exported. In “System Configuration”, we have removed the “Conversion to Data Lake” page as it is no longer needed. Additionally, the ability to change the data source by clicking on the status bar “Data Source” item has been disabled. A new option has been added to the Whiteboard Edit Node Info dialog, allowing users to disable the creation of groups for nodes that contain a single Supplier, Production, Warehouse, or Customer. The exported parquet files have new attributes names going forward, to allow for better support by data platforms like BigQuery and Databricks. The new attributes are all lower case letters (a-z) and underscores, so no more spaces and parentheses. In the generated input definition file “Parquet File Definition SC Navigator.xlsx” (see Download Parquet File Structure) and the generated output definition file “parquet-results-definition.xlsx”, both the old and the new attribute names are present. SC Navigator input parquet files support both names right now, while output files will only use the new names. Bug Fixes When running Trade-Off Analysis or CoG Trade-Off Analysis simultaneously with a Location Risk Analysis, the error message: “awf.data.aimms.session: There already exists a file or directory named…” will no longer appear.

SC Navigator 24.8.1Date July 19, 2024 Improvements The option ‘Results visible for everyone’ is now available when saving CoG Trade-Off results. On page Data - Production, 2 new tables were added with input attributes that were already in the template, but not yet visible in the app: Bill of Material Data and Production Routing Data. On page Data - Other, 3 new tables were added with input attributes that were already in the template, but not yet visible in the app: Bill of Material Groups, Mode of Transport Groups, and Use Description. On the Whiteboard, transport lanes that are not permitted, can no longer be drawn. E.g. lanes from warehouses to suppliers. Bug Fixes In version 24.7.1, attribute Inter Resource Number of Trips was added to sheet “Inter Resource Transport”, while it should have been added to sheet “Transport Cost”. It is now in that sheet, and the sheet “Inter Resource Transport” is not longer in the results file.

SC Navigator 24.7.1Date June 24, 2024 New Features The ‘CoG’ and the ‘CoG Trade-Off’ functionalities have been extended with the ability to do a Constrained CoG. The Constrained CoG allows you to perform CoG calculations, but it can include capacity constraints on the number of CoGs, the new CoG throughput, the existing Warehouses, and the existing Suppliers. Please know that a constrained CoG model is a simplified model to determine potential warehouse locations, and you are advised to run the generated CoG solution through the full SC Navigator model. More information on Constrained CoG can be found in the documentation. From now on, Scenario Batch runs can be run in parallel in the background, allowing the user to use other features of the software while waiting for the results of the Batch Run. The number of concurrent solver sessions in your license will determine how many solves can be run in parallel. Please contact your account manager if you would like to increase the number of concurrent solver sessions. Improvements On page Data - Manage Data, a new column (# Results) has been added to the tables Input Datasets and Scenarios, so that you can see the number of Results datasets that are build on top of this dataset/scenario. On page Data - Manage Data, the Results table did not show Results Dataset that somebody else created, but did not share. They are now all shown, so that they can be deleted if needed. On page Results - Transport, the ‘Number of Trips’ column is added to the ‘Primary Transportation’, ‘Secondary Transportation’, ‘Direct Transportation’, and ‘InterResource Transportation’ tables. The number of trips is calculated based on the volume and the average load size. On page Control Panel, in the Model Control table, the ‘Optimality Gap for Optimization’ value is now shown with all digits in the tooltip. Bug Fixes On pages Results - ‘Cost to Serve’ and ‘End To End’, the ‘Customer Revenue’ was the average revenue (by period) instead of the actual revenue. An “-” in the name of a custom objective could lead to a situation where the custom objective was not calculated at all. The Product Filter on production-related pages did not include all the production-related products. This issue also had an effect on the maps showing Production locations. Production locations with all products unselected were still shown on the map, and the volume shown on the tooltip of the Production location was not correct. It is now possible to download the template from the Whiteboard without location data (a warning will be given instead of a fatal error). This makes it possible to make use of Excel while providing the location data. On page Results - Transport, the Volume by Mode of Transport chart showed all transport modes instead of only the available ones. During the development of CoG Trade-Off some bugs appeared in the normal Trade-Off Analysis which are now fixed.

SC Navigator 24.6.1Date June 10, 2024 New Features The rate card functionality has been extended with two new attributes: Rate Card From and Rate Card To. This allows the user to model zone rate cards that have different prices depending on the origin (e.g. country/state) and destination (country/state) combination. For more details please read about Rate Card Related Attributes in the documentation. Improvements On the Load Data dialog page, we’ve improved the Upload Excel File experience. After selecting your Excel file, this file will directly be uploaded and you no longer have to explicitly click on the Upload widget again. This will prevent users from accidentally clicking the Load (dataset) button when trying to upload an Excel file. We have added two new sections to the SC Navigator documentation: Best Practices and Data Integration. The Best Practices section contains articles on using SC Navigator to address various supply chain challenges. The Data Integration section provides guidance on setting up data integration between SC Navigator and external data sources. We will continue to add more articles to these sections in the future. On pages Results - Cost to Serve and End to End, the System Cost is now split into four different categories: Supply System Cost, Production System Cost, Warehouse System Cost, and Transport System Cost. We have improved how some data was stored in the Azure Data Lake. As a result, the first time you open the application will take a little bit longer. In the Node Type filters, you can now filter for Customer and Supplier groups in addition to Production or Warehouse groups. This also means that if your Customer and Supplier nodes are part of a group, they will now use the new group coloring. Bug Fixes In some rare situations, AIMMS SC Navigator could throw you out of the application (bringing you back to the login page) when loading a dataset, for no reason at all. Now you can continue to use the app after the dataset is loaded. On the Edit Supplier Node Info dialog that can be accessed from within the Whiteboard page, the Supported Products selection was empty by default in case of a model without any Raw Material. Now, by default the Finished Product Group will be selected in this case. After running the Infeasibility Analyzer, the KPI Summary dialog can show a very high or low objective value. This is caused by the violation penalty that the Infeasibility Analyzer uses to solve the model. However, this information was not visible on the KPI Summary dialog. An additional row is now added to the top left table there, containing the violation penalty. The cost values are now consistent with the objective value, also when an infeasibility analysis is run.

Hi all, We are happy to announce the release of Ratio and Count constraints for the Network Design Advanced module.AIMMSian @emilyschutze wrote a blog about how you can use Ratio and Count constraints: https://www.aimms.com/story/introducing-advanced-constraints-in-aimms-sc-navigator/Do you have scenarios or use cases where ratio and/or count constraints can be used? We like to hear from you! Regards,Zoe

SC Navigator 24.5.1Date May 21, 2024 New Features Ratio constraints have been added for Suppliers, Productions, Warehouses, and Transport Lanes, allowing the SC Navigator optimization model to capture business rules better. You can use this feature via the new sheets in the template: Supplier Ratio, Production Routing Ratio, Warehouse Ratio, and Transport Ratio. You can read more about Ratio Constraint Attributes in the SC Navigator documentation. A new attribute ‘Maximum Road Distance To Retrieve’ can now be specified for any transport mode on the ‘Mode of Transport’ sheet in the template. As a result, when retrieving road distance data, if a lane is using a mode of transport for which Maximum Road Distance To Retrieve has been specified and the straight line distance for that lane is greater than the Maximum Road Distance To Retrieve, then the distance is not retrieved and the straight line distance will be used for that lane. Next to the Trade-Off Analysis that we introduced earlier this year, you can now also do a Center of Gravity Trade-Off Analysis. You can do this on the new Center of Gravity sub page ‘CoG Trade-Off’. You can set up and run multiple Center of Gravity runs here. During the runs the user can continue the work at other parts of SC Navigator and can return to check the results when the runs are ready. For more information, please read Center of Gravity Trade-Off Analysis in the documentation. Improvements A new data validation warning has been introduced to indicate whether the roundtrip attribute is used for lanes other than inter-resource lanes. The behavior of Download Solution on the Save Results Data dialog has changed. Previously, it would only export the current data to an Excel file. However, in the new version you can export multiple results datasets to a single Excel file. You can read in the documentation how to use Download Solution for downloading multiple results datasets. You can now also filter data in tables on dialog pages. For instance, this allows you to use filtering when trying to select an input or results dataset. Bug Fixes On page Trade-off Analysis, the selected secondary y-axis was not saved into the Trade-Off Analysis Results Datasets, so when the saved data was loaded, the secondary y-axis was not initialized properly. On page Center of Gravity, for the Cost Breakdown widget, the bar colors are now consistent with the legend colors. The validation logic for country codes (on the Location sheet) now checks both the “Country” and “Country Code” columns to ensure data integrity. Previously, it only checked the ‘Country’ column. If one or more of the following attributes on the Location sheet contained only empty spaces: “Street”, “City”, “Postal Code”, “State”, or “Country”, the generated geo coordinates could not be saved to the database. On page Results - End To End, the table contained a column called ‘Warehouse’. This column is now correctly named ‘Production’. The playback action of the period slider could sometimes skip periods. The element ‘cts_e2e_dummy’ was included in the “End to End Report”. This is an internally generated element that should not have been included in that report. Uploading an Excel template with extensive data in the Supplier Product sheet could be extremely slow. We have adjusted an internal solver setting to improve the performance. However, in the unlikely situation that this change negatively impacts the performance, please contact us for assistance. Previously, exporting CoGs to the SC Navigator dataset would assign excessive transportation cost data. Now, when exporting CoGs, they will inherit the relevant transportation cost data from their associated location group.

SC Navigator 24.4.1Date March 19, 2024 New Features The System Configuration app has a new page "Case Management". This allows you to move Results Datasets (that are not shared) from one user to another. This is needed, when one user leaves their role and another user is taking over this role and needs access to the saved results. Improvements Data validation is added for the Whiteboard feature. Now, before the template is downloaded, the application will automatically validate the data and if any issues are found, it will show these in dialog. Another new data validation was added to the model. It will now give an error when there is a location without any supplier, warehouse, production, or customer on it, but there is a lane defined for it. The tooltip of the "Help" button in the bottom right corner (on the status bar) now indicates that it guides you to both the documentation and the release notes. On the Save Results Data dialog for saving Trade-Off Analysis Results, the "Results visible to everyone" switch is added, such that you can now also share Trade-Off Analysis results with other users. We improved the Trade-off Analysis code from a technical point of view, such that we can modify it more easily in the future. The performance of models with a high number of locations has been improved. Bug Fixes In rare instances, after running an optimization, it is possible to receive the warning message "A problem occurred during the optimization (...)". This message occurs when the app concludes that for that specific situation, it used too strict constraints during the optimization. We have adapted the model such that the constraints are no longer too strict in this case. The "Production Routing" Minimum and Maximum Capacity were incorrectly scaled when loaded from a dataset created in version 24.2.1 up to 24.3.3. Those datasets will continue to have this problem, however after this fix newly created datasets will not have this problem. When you use "Production Routing" Minimum and/or Maximum Capacities, we advise you to reload your data from your Excel template and save it as a new dataset with this new version of SC Navigator. After the recent update of the map colors, some custom node and arc color settings were prompting a warning message stating that a color "is not an element of the checked set Map_ColorPalette". Custom map color settings will no longer cause this warning. After a dataset or results dataset was deleted, the name was not removed from all lists, so it could still be visible. On page Center of Gravity, in rare cases, the algorithm behind the Solve Max Drive Time button could result in an Error: "The model was not solved, most likely due to an infeasibility". This could happen when some locations were distant from real cities, such that the algorithm was not able to generate a viable CoG location within the specified Maximum Drive Time. These distant location are now considered themselves as possible CoG locations, such that the model that is part of the algorithm, is no longer infeasible. On page Center of Gravity - CoG Settings, in widget General Settings, the transportation speed is now used correctly when calculating the drive times in Center of Gravity. On page Center of Gravity, in the Demand/Supply Distribution map, the Center of Gravity locations were not visible when loading a CoG results dataset, although the location latitude and longitude data were visible on the CoG Run Details page. When downloading the model output, the 'Force Close' attribute would not be exported to the Supplier sheet. Transport lanes were not appearing on the reference map when comparing results datasets that contained different products. Opening and Closing Costs were not applied in single-period models. This behavior has been adjusted such that these costs will always be applied when Initial Status Closed is set to 1. It was possible that Whiteboard Results would disappear from the list where they can be loaded, this version fixes that problem for the future. However, this does not fix Whiteboard Results that have already disappeared. If that happened to you, please contact us so we can fix this manually for you.

SC Navigator 24.3.1Date February 26, 2024 New Features The Whiteboard feature has been added: a powerful tool designed to streamline supply chain modeling. This innovative feature allows you to create a diagram of your supply chain network and translate it into an Excel template. The Whiteboard enhances the speed and accuracy of supply chain modeling, while also serving as an introduction to the SC Navigator approach of capturing the behavior and configuration of real-world supply chains in a spreadsheet. More information can be found in the Whiteboard documentation. Improvements The Inventory Cover functionality has been improved by introducing "Maximum Inventory Cover". The attribute "Inventory Cover" has been renamed to "Minimum Inventory Cover". With these attributes you can set the minimum / maximum number of next periods' outflow covered in inventory. On page Results - Transportation, the Transport Results table is added, showing all transport lanes including their capacities. The node colors on the main map have been updated to improve visibility and to better distinguish between different nodes and resource groups. The old colors are still available via the widget action Customize Nodes on the main map. Bug Fixes The Enforce Base Case Constraints option was not handled correctly when applying this via the scenario functionality. As a side effect, checking or unchecking that option will be faster. The Trade-Off Analysis did not work correctly. The model would sometimes report the solution incorrectly as infeasible. The changes made in version 24.2.1 with respect to group count constraints could result in very slow performance in instances with a high number of suppliers, productions and/or warehouses. This new version resolves those slowdowns. The "Risk" attribute for custom objectives was not populated correctly when generating templates. Values were written to the column of attribute "Refundable with Limit". SC Navigator would report models with inventory and {warehouse group} capacity constraint incorrectly as infeasible. This was due to a constraint being enforced for group values, but for one variable (outflow) the flow was calculated but for the other variable (inventory) it was not. The template was not generated correctly when custom objectives had a "-" in their name. When a custom objective was renamed, its previous name was still taken into account. When capacities were only defined at the product level, the tooltips of the charts on the result pages did not show them. On page Trade-Off Analysis, the Run button could be pressed multiple times, triggering more runs than needed. On page Center of Gravity, if the option Move to Closest City was selected, the tooltip and the result tables used different names for locations. When there was a Trade-Off Analysis run in progress and a new Trade-Off Analysis run started with a newly loaded dataset, the previously started runs and the new runs were conflicted. The Data Validation was numerically more strict than the network constraints. On the Circular Flow page and the Load Optimization Results dialog, some internal names were visible. These are now properly translated to understandable names. Forced Flow data validation with active inventory was not working correctly with groups.

If you are subscribed to the Product Updates on this community, you might have received an email notification on February 2nd in which the link to the product update did not work. With today's release, the links should work properly again.  SC Navigator 24.2.1Date February 15, 2024 New Features The name of the uploaded Excel file will now be stored together with the dataset. It is shown in dataset overviews. This allows you to see what the source of the data is. The model has been extended with two attributes "Minimum Capacity" and "Maximum Capacity" on the "Production Routing" sheet. That allows you to specify the capacity for a Bill of Material. (This value is in the same capacity unit as the data on sheet "Production".) A new sheet has been added: Bill of Material Groups. This allows you to create groups of Bill of Materials, in the same way that you create Product and Supplier groups. You can use {BOM} groups for the above-mentioned Minimum Capacity and Maximum Capacity. These capacities are also shown in the Results - Production page, as well as in the Excel and Database/Parquet results. The Minimum and Maximum # of Open Suppliers/Productions/Warehouses attributes have been added to the Supplier, Production, and Warehouse sheets in the template. These allow count constraints to be added for curly bracket location, supplier, production and warehouse groups. More information on count constraints can be found in the documentation: Count and Ratio Constraints. Improvements On page Results - Warehouse, when comparing scenarios, the "Throughput, Inventory" chart groups results by dataset. After feedback from various users, we have adjusted the behavior of the model when using a Bill of Material that is specified over multiple production facilities in the "Production Routing" sheet. In previous versions, such a bill of material was required to use all facilities. The current model can pick one or more, depending on how much production capacity is needed. If desired, the old behavior can be achieved, by creating multiple Bill of Materials together with intermediate products. On page Results - KPI Overview, and on the KPI Summary page, costs for Suppliers/Productions/Warehouses have been split into three buckets - Fixed Cost, Variable Cost, and Open/Close Cost. On the KPI Summary page, the Service Widget now also contains the Cost Per UOM and the (number of) Open Suppliers/Productions/Warehouses. The capacity on the server that is used to do all the optimization requests is shared by all users that use the same cloud. Previously, all optimization requests from all users were handled with the same priority. This means that a normal optimization request that was started by one user, had the same priority as Trade-Off Analysis or Risk Analysis requests that were started by another user. So, if you started a normal request after someone else started an Analysis request, it could take a long time before your request would be processed. Now, normal optimization runs have priority over runs from Trade-Off Analysis or Risk Analysis. On page Center of Gravity, the transportation speed can be changed now. The default value is the average speed of all transportation types in the dataset. In the dialog Add CoGs to the set of Warehouses, the values for Warehouse Group for CoGs and Location Group for CoGs are now initialized with the CoG Location Group/CoG Warehouse Group value provided in the template. We have removed the "Solution found" dialog message at the end of a Solve Max Drive Time run, to prevent an unnecessary click. By default, Suppliers are no longer included in the CoG calculations as many users ran into the warning Warning infinite capacity treated as zero. If you want to include suppliers, please select them again on page CoG Settings. You can now edit the Center of Gravity Wiggle Factor parameter. The initial value is set to the average of the Transportation Wiggle factor in input data. The tooltip for the CoG Weight Factor now includes a brief explanation of what this parameter controls. When exporting CoG locations, the CoG Primary/Secondary Transport Cost values will be used to populate the 'Cost Per Distance' for primary or secondary lanes connecting the exported CoG locations. This ensures consistency between the parameters used in the Center of Gravity analysis and the exported data to be used in subsequent network optimization workflows. SC Navigator could report models with inventory and {warehouse group} capacity constraints incorrectly as infeasible. Bug Fixes In some cases, saving the results datasets could be much slower in SC Navigator version 24.1.1, compared to the previous version. The Weighted Average Lead Time on the KPI Summary dialog was using the Maximum lead time, instead of the actual lead time. On page Results, the coloring in the Reference Result map was not correct. It used the same coloring as the Active Result map, while it should color based on the data of the Reference Result dataset. The calculation of Rate Card cost was not correct when lanes were defined with curly brackets. In that case, some costs were duplicated. The data validation executed after Add CoGs to the set of Warehouses could give incorrect data validation errors and warnings. The Trade-Off Analysis did not work correctly when having more than 10 runs and some of the runs would be marked as infeasible incorrectly. The model could incorrectly generate this warning when loading a dataset: There exists a warehouse that has 'Inventory Cover', but no 'Available (Inventory)' for next period.

SC Navigator 24.1.1Date January 11, 2024 New Features Risk Analysis simulates closing each location, one at a time, and assesses the corresponding impact. This will help you in finding the vulnerabilities of your supply chain. More information about the Risk Analysis can be found in the documentation: Risk Analysis. With Trade-Off Analysis you can do multiple solves, each with a different setup, and find the best trade-off between your KPIs. More information about the Trade-Off Analysis can be found in the documentation: Trade-Off Analysis. Improvements Previously, some pages displayed raw coding names instead of proper text. These have now been replaced with appropriate texts across all pages. The pages "Geocodes" and "Distance" are now also available when the data is loaded from a dataset. In that case, the data on these pages is read-only. The icons for the primary page actions on page "Geocodes" and "Distance", have been replaced by icons that match the action, instead of the generic AIMMS logo. Links to the latest e-learning material have been added to the template. Solving time for datasets with Single Sourcing data is decreased in case of both active and relaxed optimization options. The SC Navigator version numbering has changed. From now on, the first number will refer to the year in which the version was released. The second number still increases with every feature release. The third number increases for bug fix releases. Bug Fixes The data validation warning that appeared when a minimum number of Suppliers/Productions/Warehouses/Locations was provided without a maximum, is removed. When a results scenario was saved right after a Full Solution Export, the scenario did not appear in the list of results scenarios.

SC Navigator 4.05.01Date November 30, 2023 New Features From this version on, data can be stored in Parquet files in Azure Data Lake Storage. Using Parquet files allows for easier integration with other systems in your organization. Furthermore, reading and writing datasets can be faster, especially for larger datasets. We will contact you to plan when we will setup Data Lake Storage and convert your existing database to Parquet files. Improvements Data validation has been added for the case when the Maximum # of Source Locations data for customers is provided on the Product Location sheet. Please make sure to provide the Maximum # of Source Locations data for customers on the Customer Product Data sheet instead. The generated summary for scenarios has been improved to provide a clearer representation of the contents within each scenario. On page Results - Transport, the Rate Card Band results are now visible. On page Results - End To End, filters now operate independently from the filters on other pages, providing increased flexibility to alter the view. Additionally, a filtered icon indicator has been added for enhanced visibility. Bug Fixes In the Batch Run functionality, an error could occur when the solution was being saved to the database and the auto-generated scenario name was excessively long. As a result, the batch run process came to a halt because the long name could not be stored in the database. Now the app is able to automatically truncate the name into a shorter text, and include the original name as description. When comparing Results datasets, the KPI Summary dialog now shows the Results datasets in the columns instead of the rows in a table. On page Control Panel, the Model Control table now displays the section separation lines well when comparing multiple (newly saved) Results datasets. On page Data - Transport, in the Transportation Data table the Force Open and Force Close columns are now always visible. On page Results - Customer, the unserved demand is excluded from the lead time violation and the drive time distribution. In this case the drive time is not shown (zero). On page Results - Customer, if the demand is transported to a customer with zero distance, the drive time was incorrectly -inf. Now in this case the drive time is not shown (meaning: it is zero). When using side panel filters, the count of the Select/Deselect buttons were inaccurate and the clicking on the Deselect button would give an error message. On page Results, the tooltip for nodes on the map now shows the location description if the Use Description Location attribute is set. On page Data - Manage Data, when deleting one or more items, the text in the confirmation dialog is more accurate. On page Results - Production, clicking on a production in the bottom left chart, did not update the other charts based on this selection.

SC Navigator 4.04.01Date October 23, 2023 New Features The Center of Gravity App has been integrated into the SC Navigator App. This brings a streamlined process enabling analyzing Centers of Gravity within the same dataset and application. When there is a circular flow in the solution, a new page "Circular Flows" will show up. This page will help you finding the cause of the circular flow, such that it can be fixed in the input data. Improvements On page Scenario - Control Panel, more attributes can be handled. On page Results, colors of the node types have been changed to colors used in Network Design, and their icons also have changed for easier identification. On page Results, the View options side panel now shows the colored icons in the Filter By Node Type widget. This allows you to quickly identify the node type of nodes on the Results map. On page Data - Manage Data, the Scenarios table now includes an auto-generated scenario summary. This summary provides quick insights into each scenario without additional loading actions. The Save Scenario Dialog and the Load Scenario Dialog show this summary as well. Please note that the summary is only available for new scenarios. Data validation has been added in case the Average Load Size data is missing for a row with Cost Per Distance / Cost Per Trip / Minimum Cost Per Trip. Bug Fixes The list of Result Datasets that are generated during a batch solve, was not displayed correctly. The changes made in version 4.03.04 with respect to the E2E volumes could result in very slow performance in some instances. This new version will be faster than before, although it will be slower than before 4.03.04. The following data validation messages will no longer occur when the Available data is missing for a row with a curly bracket group in it: "WARNING: There are one or more attributes defined for (<combination including a curly bracket group>). However, this <warehouse/supplier> is not available for this product. You can make it available by specifying the 'Available' attribute on sheet '<Warehouse/Supplier (Product)>'." The data validation for Base Case Volumes now shows an error when Base Case Volumes on a last mile lane are different from the sum of demands at the customer location where the lane goes to. On page Results - Transport, the charts incorrectly displayed a duplicate transportation volume due to the inclusion of both product groups and individual products in the calculation of transportation data. On page Data - Transport, the Custom Objective input data for transport step was not visible when the data was not (yet) saved to the database. On page Scenario - Transport, the Relative Change value was not being applied properly. On page Scenario - Production, the adjustment data related to the Bill of Resource data was not being saved correctly. On page Data - Warehouse, in the Inventory (Product) Data tables the Force Open and Force Close columns are now always visible. On dialog page Custom Objective settings, the 'Include in model objective' variable can now only have binary values.

In this post, I like to highlight the main developments that we will be focusing on in 2022. This roadmap has been created based on various inputs, including many customer & partner discussions, stakeholder interviews we did in 2021, incoming requests, and market trends so we can provide an even greater impact and more benefits to you and your users. In addition, these inputs have allowed us to adjust and finetune our product vision.  An important component of our vision is that we want to provide you AIMMS as a complete service in the Cloud where customers can find ready to go Supply Chain applications, run their end-to-end optimization practices using bespoke applications, and partners are able to build a thriving business. This means, we have adopted a Cloud-first strategy with a strong focus on deployment of applications and optimization engines (API-based), and the integration of external services (be it data, machine learning or AI). We want to allow more connected and integrated decision making such that more impact can be achieved by a growing community of users, easily.  In our Cloud-first strategy, we are also moving from AWS to Azure to benefit from the partnership Microsoft can offer to us and to many of our customers.In the Roadmap 2022 table below you can see that some of these items are not exactly specified yet as they also depend on our customer use cases and feedback during development. For example, in the AI/ML incorporation, as well as the understanding of optimization results, we are looking forward to your input. So please do reach out to us if you have specific use cases you are looking to address, or respond to requests and use the ideation on this community.  Timing of all initiatives is purely indicative; we’ll update this table as frequently as possible.It’s good to know that next to those main developments, lots of smaller improvements are developed and released on a regular basis. In addition, we are continuously improving our architecture to assure maintainable, and robustness of use. As always, you can expect from us to stay up to date with the latest solvers. Please be sure to regularly check the release notes of our various products you use.  Table updated July 4, 2022 Focus Area Details Q1 Q2 Q3 Q4 Next Gen SC Navigator Our next generation supply chain application consolidating our existing apps and delivering; improved UX for working with scenarios, more optimization options, improved inventory modeling, and improved data modeling.       Beta Data Exchange Library Multi-functional library to generate both REST API servers and clients and easily map data onto AIMMS models, designed to minimize the programming effort for app developers (OAuth, OpenAPI, …) More details here.

Curious about the features and product updates our team released in 2021? We collected the highlights below.  AIMMS Development   AIMMS Community Edition Since its launch in March 2021, many users around the world are using AIMMS Community Edition! In case you haven’t requested yours yet, this free AIMMS license gives you access to our extensive capabilities for model diagnostics, data connectivity, web application building and visualization, case management features, and more. AIMMS Community Edition also includes access to the open source solvers CBC (for linear and mixed-integer problems), and IPOPT (for nonlinear problems), as well as the AOA solver (for mixed-integer nonlinear problems). It’s ideal for personal projects and training purposes. Request AIMMS Community Edition todayWebUI  We released a new Application Management capability as experimental feature in February and released this as a standard feature in September. This allows you to more easily copy, move and rename widgets on your pages.  Read more   The Grid Layout became a standard feature in July. This gives you far better control over where widgets are placed on your pages, dialogs, and side panels using pre-defined or custom layout templates. Read more  You can now download widget contents as an image - one of the many ideas submitted in our community.   You can now add custom tooltips for the X-, Y- and Size labels in your Bubble Chart widgets, which can further increase the clarity of the data that you are presenting to your users in this widget type. We also added support for custom tooltips to the Button, Upload and  Download widgets – another idea submitted in our community.  We announced a new WebUI Widget Framework, which will make widgets more flexible, robust, and easy to use for us and our users to manage, and hosted a live product update to provide a demo of upcoming features.     We extended the Text Widget to support a string parameter as its content. This means that you can now dynamically specify the content of this widget.  PLUS we would love your feedback on the new widget types we are building. Take a short survey.  For a complete overview of new features, check out this page.  Algorithmic Capabilities As of this summer, Gurobi can now be used on applications running on the AIMMS Cloud Platform - thanks to Gurobi’s new Web License Service (WLS). This expanded the choice of solvers you have across AIMMS products. In AIMMS 4.83 (released in November), we added support for Gurobi 9.5, which comes with performance improvements for LP, MIP, MIQP models and for convex and non-convex MIQCP models. This release also shipped with the following:For most GMP procedures used to modify columns, rows or coefficients, we added a ‘raw’ variant which uses a set of columns and/or row numbers as input. You can now use a new procedure GMP::SolverSession::GetIIS to retrieve an irreducible infeasible set (IIS) for an infeasible math program. It returns the row and column numbers of the rows and columns in the IIS. The IIS will be calculated by the solver and is supported by CPLEX, Gurobi and BARON.Besides this, we released other algorithmic capabilities this year, such as:  The use of quadratic structures in solvers, including Knitro 12.3 (or higher)  Support for blockmatrices in submodels  For more information about the latest algorithmic capabilities, click here.   Data Exchange Library The Data Exchange library now enables you to expose procedures in your model through a REST API. We also announced several improvements in the Data Exchange library last month, including:  A new annotation-based JSONDocument generator that creates a mapping for a standardized nested JSON document to read and write all data for a given collection of identifiers in a model.  A new function dex::ResetMappingData() to empty all identifiers, sets, and reset counters used in a particular mapping.    AIMMS Network Design  We started the year by revamping the user experience in AIMMS Network Design, check out this post for details.  You can now generate Geocodes, Trip Times and Distances automatically.   We released features to make maps in AIMMS Network Design more customizable, easier to use, and visually appealing.  The app now enables you to model non-financial objectives, like carbon emissions and power consumption, to assess sustainability trade-offs. Watch a demo and learn more  AIMMS Docs: Now open source  We opened our documentation’s source code in an effort to make it easier for users to provide feedback and contribute to the improvement of our products. Read more  AIMMS Academy: More training possibilitiesThis year, we expanded the course offering on AIMMS Academy to include:Error Handling WebUI Advanced User Interaction  Inventory Planning Execution Efficiency Remember that you can get certified in several of our courses. Enroll today! 

You now have the ability to model non-financial objectives, such as carbon emissions and other sustainability goals, in AIMMS Network Design. Using the custom objectives functionality, you can now define objectives in units of measure other than costs (for example, carbon emissions in tons). You also have the ability to run scenarios to evaluate the trade-offs between financial and non-financial metrics, and apply to constraints to both, in order to find the right trade-offs between costs and carbon emissions. This is the first release of this functionality, more enhancements and functionality on this topic will follow in future releases.  Please feel free to let us know if you have ideas in this regard by replying to this post, or sharing your ideas in the Ideation section. See a demo and tutorial of this feature in our Network Design user group 

We have added a new functionality called Take or Pay in Network Design. This feature is useful when you have a type of contract where you are forced to ‘take’ a certain amount of volume from a supplier at a given cost or ‘pay’ the supplier if you decide not to take the volume.  To add the option in your template you must activate the take or pay fixed cost of transportation option within the Cost component section of your Configuration.Learn more about this feature in a Tutorial on our Network Design user group page

Update: the features in this article were released on April 21, 2021 - Read the release notesIn the next release of the Network Design app, we will add some features that make the map more customizable, easier to use, and visually appealing.  Below is a short demo video to get you started using these new features :Customize nodes and lines (size, color, icons, etc) Filter which information is displayed on the map Show DC service areas in different colors, etc Show node and arc information in hover boxes Save and recall custom map zooms Overlay heat mapsSee a demo on our Network Design user group page 

We have released a new version of AIMMS Network Design, with functionality that enables you to model more complex constraints in an easier manner. Example use cases of how these new constraints can be used include:cross country/state restrictions different resources for slow movers/fast movers open/close multiple DC types and production lines at a single location simultaneously restricting certain modes of transport from entering or leaving a resourceWatch the demo video on our Network Design user group page 

Update: these new features have been released in AIMMS SC Navigator 2.27.01. This topic has been updated with more information.We have integrated the GIS data service LocationIQ into Data Navigator and have built significant new functionality that will allow you to automatically generate geocodes together with real trip times and distances in AIMMS Network Design. This has two important benefits:  Geo-Coding :  In addition to importing latitude and longitude directly, you can now import address data (country, state, city, street and zip code), and then use the geocoding function in Data Navigator to generate geo-codes based on the address data. You can now also manage the quality of the geocodes generated.  Trip times and distances  In addition to importing actual trip times (used for lead time constraints) and distances (used for cost per km or cost per mile transport costing), you can now generate these automatically in Data Navigator.  You can also adjust these for different modes of transport. Moreover, it’s now possible to combine straight lines (plus a user configurable factor), input data, and data generated by LocationIQ in a way that makes sense for your model. Watch the demo video on our Network Design user group page  

 Update: The UX enhancements announced in this post were released in SC Navigator 2.26.01. Read the release notes.As we mentioned in January, our next release of Network Design and Center of Gravity will come with a UX revamp. We also made exciting changes to the Data Navigator UX. Highlights include:A new side panel on the left for improved navigation   A status bar for easy access to data configurations and applications Handy overview of data issues, with colors that flag the most urgent ones A new in-product help feature for improved access to supporting documentationCheck out the video below to see the new UX in action. We expect this to be released in the next few days. Keep an eye on your inbox or watch this space for updated release information. If you need help navigating these changes, contact support@aimms.com. 

 Update: The UX enhancements announced in this post were released in SC Navigator 2.26.01. Read the release notes.Our next SC Navigator release will include a complete UX overhaul for Network Design and Center of Gravity. Among other things, we added the following to make the user experience as pleasant as possible:Workflows Side Panels Status Bars Widget Actions Filters The new user experience should be self-explanatory, but things will look a bit different. Watch the video below to get acquainted with the new interface.  Got feedback or questions? Feel free to leave a comment below. If you need assistance with the new UX once it’s released, please do reach out at support@aimms.com. 

In July, we shared the most popular new features released in the first half of the year. Today, as 2020 draws to a close, we’re happy to bring you another collection of features - Volume 2 in our product greatest hits!  Integrations for AIMMS and Scripting languages like Python You can now easily include the power of Python (and other scripting languages) into your AIMMS model, for example to pre-process input data using Machine Learning. We released a combination of libraries and documentation to give you ultimate flexibility in using the (scripting) service of the choice. Learn about these resources here. Curious about the benefits of combining machine learning and AIMMS? Read this article.   AIMMS Developer New features  AIMMS 4.75 and AIMMS 4.76 were action-packed releases with new features. Highlights include: The Grid Page Layout, which introduces the CSS Grid concept of visualization in page layouts - a widely-used standard in web design. Table filtering options, which allow you to narrow down the data in your table, helping you view only the information you need. Date-Time Picker, which makes it easy to differentiate between dates and maintain a reference when dates are used in tables. TimeZone support to configure multi-user time zone applications, ideal for teams using apps in several locations across the world.Check out these best practices and a working example for multi-time zone applicationsKnitro 12, the latest version of this solver. Bar-line Chart, a new visualization feature that’s in high demand.  New Data Exchange Library   We also launched version 1.1. of the new Data Exchange Library (Version 1 shipped on July 2020). This version now also supports read/write capabilities to and from Excel and comes with improved (auto-)mapping features. To be precise, we added:   The ability to read/write tables to Excel, one table per sheet.   The ability to auto-generate mappings for JSON, XML, CSV and Excel based on model annotations, as well as new mapping attributes to support this.    AIMMS Network Design Bill of Materials modeling and Custom Costs shipped in AIMMS Network Design AIMMS Network Design now includes Bill of Materials modeling. This allows you to configure the Bill of Materials (BOM) and specify production conversions, extending your modeling capability to the end-to-end supply chain (including raw materials and intermediate products). Custom costs can also be added at all points in the supply chain where physical costs are incurred. Example use cases are the addition of taxes and duties, carbon costs and inventory holding costs to the optimization. Check out this tutorial and learn to model Bill of Materials and Custom Costs in AIMMS Network Design Data ValidationWe added validation checks to trap common data mistakes before they are imported. Improved Control Panel and Spreadsheet templateWe extended control over scenarios from the control panel in the browser so that the user can spend less time in the Excel template, and more time in the browser to configure scenarios. We also made changes to the input data template to make it more intuitive and easier to capture data required by the model.Transport costingWe added further capability to model transport costs such as stepwise cost functions, and take or pay arrangementsData separationWe added the ability to separate data between different business units and projects in the same environment.UX 2.0: We are nearly complete with the UX (User Experience) upgrade for both Network Design and Center of Gravity, announced in last month’s update. In January 2021, you can expect workflows, side panels, status bars and other enhancements that will improve the user experience in the apps.
