    Control over the frequency of the vertical lines in a Gantt ChartImplemented

    On behalf of a customer, I forward the following idea: As a model builder, I would like to control the grid resolution in the Gantt Chart.  For instance, in the image below, I would like to draw a vertical grey line every hour, instead of every 3 hours.WebUI from enclosed AIMMS 4.85 projectThe associated AIMMS 4.85 project is attached.

    WebUI Gantt chart: showing overlapping tasks on separate linesImplemented

    In several of our planning applications (currently built in AIMMS WinUI, discussion ongoing to rebuild them in WebUI), we have resources which can perform multiple tasks at once, and the planner needs to have a good overview of which tasks those resources are doing. In the WinUI, these tasks are shown on separate ‘lines’ in the Gantt chart (all belonging to the same resource, see first screenshot below) so it is possible to quickly get an overview of them all, read the text in the bar, easily click on or hover over a specific one, and approximately judge how many there are in parallel. In the WebUI, these tasks overlap (see second screenshot below, from the documentation), making the above much harder or even impossible.Would it be possible to change this, or add a setting such that the user can select whether he/she wants the bars to overlap or not?Thanks! WinUI: WebUI:

    Show week numbers in WebUI Gantt chartImplemented

    Many of our customers, for example in the manufacturing, high-tech or logistics industries, work with and communicate in week numbers instead of dates (so ‘week 41’ instead of ‘August 24’). Unfortunately, in the WebUI Gantt chart currently only dates can be shown (as far as I can see), which makes it very inconvenient to work with for these customers, as users constantly need to convert dates to week numbers and back. Would it be possible to show both dates and week numbers, as is currently possible in WinUI Gantt chart? Or if not, to make this a setting such that one can choose to see week numbers instead of dates? Thanks!

    Delete widget from page tabImplemented

    Sometimes we need to delete widget. But it is only possible from “App” tab, not from “Page” tab. While in “App” we cannot see which one is unassigned. Good to have option to delete widget from “Page” tab. Or maybe just give marks in App tab to identify which widgets are not used.

    Support for Invoking Constraints by Library Scope (e.g., A:Constraints)Implemented

    Suppose A is my library/module.  It would be very useful if AIMMS allowed modelers to programmatically reference or collect constraints/variables defined within a specific library/module e.g., A::Constraints or A.getAllConstraints()” which would return the set of constraints that are in A. This would enable better modularization, selective model construction, and more scalable large-model development.I know there are workarounds this, like choosing constraints by a binary parameter, defining a set for the constraints you want to include, etc. but they all require manual overhead and careful maintenance effort. Best,Gorkem

    WebUI pages defined in librariesImplemented

    Hello, I was wondering if there is a way to create a WebUI page and save it in a library module.  My goal was to update an old WinUI page that we use in a library, transform it to a WebUI page, and distribute the library to other projects so they can also use the WebUI page. If there isn’t a way, I think this is a great feature to add. “As a developer (role) I need to be able to define WebUI pages in libraries (functionality), so I can distribute WebUI pages to other projects, the same way WinUI pages work currently (goal).”

    Can we make pages inactive (but visible in the menu)?Implemented

    I often use the first page as sort of "section header" to indicate the common topic of its child pages. Usually, this "header page" contains nothing, but can be opened. This is confusing. Could we make this page visible, yet unclickable?

    Enhanced Search to include WebUIImplemented

    The global search (<ctrl>+<shift>+<f>) searches the aimms project, but does not search the webui json file. This means I usually end up searching in aimms and then searching the same thing in a text editor with the json file open. It would be much more convenient if both could be searched within aimms.

    SCN: Always show input columnsImplemented

    As an end user I need the input columns always being shown, so I can easier change data and run scenarios.If you have not put any data in some columns (like Minimum Capacity) in the template, these columns are not shown in the input tables.

    SC Navigator: errata and improvements for the data input templateImplemented

    The file “Template SC Navigator.xlsx” would benefit from the following changes:Errata: On the [Notes] worksheet lines 36-37 are duplicates of lines 34-35 and the “Jump to Attribute” links do not work.Suggested improvements:Add an introductory worksheet to explain the color coding used on the [Notes] worksheet, the worksheet tabs, and the attribute columns on various worksheets. Add a table of contents worksheet with links to individual worksheets. This would be similar to the “Jump to Attribute” functionality on the [Notes] worksheet but would be specifically for worksheets. Lock to top row and add a filter on all worksheets. Wrap text and change column widths so that field names and descriptions have more space and can be read without having to select the cell. On the worksheets [Single Value Data], [Single Value String Data], [Settings] & [String Settings], align the entries in column A with the entries in column D. Remove extraneous blank columns like columns F:M on worksheet [Single Value Data] and columns N:P on [Periods]. Use the Outline feature to group the Attribute columns on worksheets and permit the columns to be easily hidden so the descriptions to the right can be easily read. Here is a version of the template that includes these improvements. Template SC Navigator_with ToC.xlsxHere is a version that also has macros to facilitate navigating the workbook. Template SC Navigator_with ToC.xlsm Note: The Table of Contents was created with an Excel add-in called ASAP Utilities.

    Table V2 - Specify read-only via the defaultImplemented

    Hi,Really nice that we can now specify the decimal places and read-only attribute per identifier. What I miss, however, is setting the read-only status via the defaults (like we can with decimal places and show units). Could you include this please? It would be very efficient if we can put the entire content of a table to read-only with a single setting.Thank you and regards,

    Set decimals per identifierImplemented

    It would be very useful if we could set the number of decimals per identifier in the webui tables, so we could have some columns with 0 and 2 decimals.

    Skip Cost to Serve calculationImplemented

    I'd like to have the possibility to skip the Cost to Serve calculation. In 95% of the runs I'm not interested in the Cost to Serve results, and it could take a significant amount of time (in some instances as long as the optimization). Would be great if a user could set CtS calculation On/Off in the Control Panel.

    Wrap header names in webui tableImplemented

    Can it be possible to wrap the header names in the webui tabel widget?Especially when the data itself has not that many characters, I prefer the header to be wrapped instead of making the column wider. And is it possible to turn the header direction (from top to bottom for example?

    Upload multiple files at once (not via ZIP) / single-click upload functionImplemented

    This idea relates to the upload widget of the AIMMS WebUI. At the moment this is a double-click process. To increase user-friendliness a single-click process would be more convenient.In addition to this, files can only be selected one by one in the current feature. A nice addition would be to upload multiple files at once (not via ZIP)

    Remove the need to click the upload button twice when uploading a file to webIUImplemented

    Hello!Currently, in order to upload a file to WebUI, the user first needs to click the upload button, which then opens up the file selector. Once the file is selected, the user needs to click that same button once again. Otherwise, the upoad process will not be completed.We feel that this is a counterintuitive feature, and many of our end-users have made remarks on this topic, asking if it would be possible to remove the third step. In that way, once the users select the file and click the "open" button, the file would automatically upload, removing the need to click the upload button a second time. Step 1: Click the upload buttonStep 2: select a file and click “open”Step 3 (the one we would like to remove): click the upload button once again Would that be possible?Thank you!

    Use the text attribute (or similar) of an identifier to automatically set a "pretty name" in WebUIImplemented

    We can of course modify the <model name>.properties file in ~\MainProject\WebUI\resources, but as this is a feature which we probably want for all parameters shown in the WebUI, could this be made more developer-friendly? This would also resolve that we have to update the .properties file when we changed the name of an identifier. Perhaps this could even be done in such a way that we could use string parameters for this “pretty name” which allows them to change dynamically. In this case, I think we don't want to be forced to use string parameters (as this would result in a lot of additional parameters), but we should be able to also use a static string.

    Standardizing data exchange with AIMMSImplemented

    The DataExchange library (https://documentation.aimms.com/dataexchange/index.html) is intended to offer support in AIMMS for data formats, such as JSON, XML and CSV, that are commonly used in web services. The basic mechanism to read and write data using the DataExchange library is to provide a mapping that maps data in any of these formats onto identifiers in an AIMMS model. Although creating such a mapping is not very difficult, it may amount to a lot of work. In this post I want to explore if and how we can provide some kind of standard format, that is generated by the DataExchange library itself, and can be used directly in most use cases for web services. More specifically, I'm looking for feedback on what follows below.Let's start with a list of possible web services that we could consider:Calling a web service from within an AIMMS model that runs a Python/R script with data from within the model.  Calling an (AIMMS-provided) web service that runs an AIMMS model on our cloud platform, with data provided from the calling program/service Calling a web service to store data from a model, or retrieve data needed for a model (such a web service could, for instance, replace the current database interface in AIMMS and prevent all kind of problems with, for instance, latency that our current database interface suffers from regularly, as the web service could be placed close to the database server)Let's focus on the last use case, and explore how most of our customers use relational databases (as we do ourselves as well in AIMMS SC Navigator). Most customers store values from one or more identifiers with the same domain in a single table. In order to be able to store data for multiple scenarios, typically one additional column is added to the primary key of all tables to store the scenario key. Typically, models read data from such tables for one or more scenarios, and add the complete data for a new scenario, or replace the complete data for an already existing scenario. Changing individual rows or rows, has quite some commonality with CDM and are less suitable for the regular database interface we have in my opinion. In SC Navigator, we have an additional layer of abstraction, the dataset, which collects data from multiple tables holding functionally similar data into a single dataset instance. The model data is then filled by mixing and matching data from instances of multiple datasets, each of which could have been created by any of the SC Navigator apps, or, with a 'database' web service, even by external applications/services. Through model annotations we can indicate in the model the data of which identifiers should be stored in a single table, and to which dataset such a table would belong. From such a collection of annotations we could automatically generate a database schema (like in tools such as Mendix), and use DataExchange functionality to write data to these generated tables either directly, or via a webservice. The big benefit is that the entire data exchange with a model is standardized, and we can make sure that the data exchange with the database will take place in a performant manner, by proper normalization of all tables and the use of the appropriate indexes on the database tables. We could even let CDM operate on such generated tables, where one would lose the history of changes that CDM currently provides because only the latest value will be stored, but where individual changes committed by one client could still be passed to other clients as CDM currently does.To transfer the data as JSON, we could generate a mapping from those annotations that generates JSON as in the following example:{ "dataSets": {   "DataSet1": {     "instance" : "data of 07-09-2020"     "tables": {       "Table1": {         "rows": [                 { "i":"i1", "j":1, "pn": 10.0, "ps": "a value"},                 { "i":"i1", "j":2, "pn": 20.1, "ps": "another value"}         ]       },       "Table2": {         "rows": [                 { "i":"i1", "j":1, "k":3, "qn": 10.0, "qs": "a value"},                 { "i":"i1", "j":2, "k":4, "qn": 20.1, "qs": "another value"}         ]       }     }   },   "DataSet2": {     "instance" : "data of 07-09-2020"     "tables": {       "Table3": {         "rows": [                 { "i":"i1", "rn": 10.0, "rs": "a value"},                 { "i":"i2", "rn": 20.1, "rs": "another value"}         ]       },       "Table4": {         "rows": [                 { "i":"i1", "k":3, "sn": 10.0, "ss": "a value"},                 { "i":"i1", "k":4, "sn": 20.1, "ss": "another value"}         ]       }     }   } }}Such a "standard" JSON format to exchange data is quite suitable for exchanging data with an AIMMS model-based webservice and can be easily generated from other applications/services, but also with Python webservices, as the JSON content of the individual tables can be directly read into or generated from Python Pandas. And it matches directly the format of the generated database table I proposed above (with potentially some metadata added in additional fields). So, to summarize the benefits of my proposal:it standardizes all data exchange with the model, database and external web services. This fits our guidance principle, where AIMMS will provide as much guidance as possible to create good applications and follow best practices for modelers the work to create mappings to exchange data with various services will dramatically reduce it would alleviate modelers from the task of manually creating a performant database schema and the associated mapping in the model it will make sure that, because of the standardization, we can much more streamline the support AIMMS have to give on data exchange with databases.Please let me know your reactions.

    Extended GMP Get functionsImplemented

    In Generated Math Programs one can adjust (Set) or retrieve (Get) e.g. coefficients, right hand sides etc. For the “Set’ part, we have a number of Multi functions that allows you to adjust more than 1 row, column, coefficient in 1-go. We are wondering whether similar functionality for Get would be valuable and what your use case is. Can you let us know by voting and commenting below?We are specifically thinking about the following functions that are currently element based (you might think of others as well):GMP::Coefficient::Get GMP::Row::GetRightHandSide GMP::Column::GetLowerBound GMP::Column::GetUpperBoundThe multi routines will use indices in the sets of column numbers and row numbers as arguments (these sets can be obtained by using GMP::Instance::GetColumnNumbers and GMP::Instance::GetRowNumbers). The data will be stored in a parameter using the same indices. See also:Coefficient: https://documentation.aimms.com/functionreference/algorithmic-capabilities/the-gmp-library/gmp_coefficient-procedures-and-functions/index.htmlRow: https://documentation.aimms.com/functionreference/algorithmic-capabilities/the-gmp-library/gmp_row-procedures-and-functions/index.htmlColumn: https://documentation.aimms.com/functionreference/algorithmic-capabilities/the-gmp-library/gmp_column-procedures-and-functions/index.html

    Two step verification login access for PRO portalImplemented

    Hi all, Data security is always top of mind for a lot of companies of course and therefore also when using AIMMS apps. Therefore I would like to pitch the idea of a two-step verification method for the PRO portal.We as a company are working with SAML access for the PRO portal for our own employees and therefore securing two-step verification. But we also work together with consultants. They also need access to the PRO portal, but can’t get a company identity. The only option there is now is creating a user profile for them with only a password as a security measure. Therefore I would like to see two-step verification as an option for the PRO portal, such that any data accessible through the Apps in the PRO portal is more secure.
