How about an LLM-powered PRO Jobs Page?

We are rebuilding the PRO Jobs Page, see also this post.While working on that another idea came up, replacing the 'filtered list’ of the current Jobs Page with a LLM-powered chat. And we generated a ‘paper prototype’ of this. Can you please take a look and let us know:what pros and what cons do you recognize? would you prefer this over the current ‘filtered list’? suppose we would offer it as an alternative, for what tasks would you use it and for which ones use the ‘filtered list’?Here is the ‘paper prototype’, illustrating various dialogues from various roles.  Each dialogue is designed to address the specific needs of the user role, demonstrating the AI-powered chat's ability to understand context and provide actionable information and solutions. We trust that with that it is self-explanatory.Thanks for your help!Paper Prototype for Jobs Page powered by GenAI Dialogue 1: End User - Checking Task Status User: Hi, can you tell me the status of my current sessions?  AI: Of course!

Reverting WebUI layout

How can I revert an app on PRO back to it's original ( as designed by the developer ) layout? I know in the older versions of AIMMS you had the possibility to click on your name and you had the option to revert the layout: 4.44:   In newer versions of AIMMS I don't see this option anymore. Has this option been (re)moved? 4.71:

AIMMS PRO Cloud IP addresses

Is it possible to get a list of the IP addresses from which AIMMS PRO Cloud calls would come?E.g. if in your model you are using DEX to make a call to a web API endpoint, what is the IP address / IP range it comes from?Knowing this address/range could be used to restrict the access to the API endpoint to only AIMMS PRO platform instead of opening it up to the complete internet (which would add an additional layer of security besides oauth2 authentication)

Unexpected reference to old identifier on PRO

Hi community!We recently merged our develop branch into a feature branch causing a name change in one of our model identifiers (spLaneDataFolderName). Due to this merge, we observe a startup error on PRO, complaining that "awf.data.aimms.session:spLaneDataFolderName : Unknown identifier: spLaneDataFolderName (in widget 'scalar_welcome'). (widget: [object Object], status code: 400)". We do not expect any errors on PRO here, as:locally we do not get an error, the identifier is renamed correctly in the nch file and the old identifier name is referenced nowhere in the main project as it should (only in some old .data files which are not included in the .aimmspack and in the nch file) We already tried removing and re-adding this identifier to the widget and re-releasing. Can you help us resolve this old reference error which only occurs on PRO?

PRO on premise postgreSQL database gets upgraded to 16.2 - how to upgrade your PRO on premise set up on your own?

Starting with AIMMS PRO 24.5.1, the postgresql database version is updated to Postgresql 16.2 for Windows installation. This means when upgrading to AIMMS PRO 24.5.1 and newer, you will need to migrate your pro postgresql database, which adds a step to the upgrade process.The following steps explain how you can do this using AIMMS PRO Configurator >> Backup Management:Preparation and backing up the old database:For example, current PRO Installation is 24.1.1.7 (old postgresql db - Postgresql 9.3)Before you proceed to installing the newest PRO version open the pro Configurator and take a database backup using Configurator >> Backup management >> Backup Now Make sure backup is created (i.e. compressed (.zipped) folder under C:\ProgramData\AimmsPRO\Backup\aimms-pro-24.1.1.7-3rrf1z2-2024.03.14_14.53.04.20.zip) Copy (or take a screenshot of) all Configuration Settings (Connection configuration, PRO Configuration and Backup management tabs) such that you can copy them to th

Download older AIMMS Pro executables

Hi all, We currently have an AIMMS Pro on-premise installation which we need to upgrade to a newer AIMMS Pro version. We would like to upgrade to AIMMS PRO 24.4.2.1. The reason is we're in a bit of a hurry to finish the upgrade and want to minimize the risk (as we’re coming from a relatively old version), so we do not want to upgrade to a higher version to avoid having to migrate the AIMMS PRO database at version 24.5.1.However, on the AIMMS download website we seem to only be able to download the latest version of AIMMS Pro, even though in the past it was possible to also download older versions (and of course it is also possible to download older versions of AIMMS Developer).Can someone help us in finding the executable for AIMMS Pro 24.4.2.1? Thanks!Meike

User logging report for On-Premise PRO server

Hi all!  For an on-premise AIMMS PRO server, does anyone know if there's a way to get a report of the last time each user logged in or the last time each user opened a WebUI session? I know it's possible to search and parse logs (at least over the available history), but wondering if there's an easier way.  The AIMMS Control Panel can create a session list by user (Session List tab), but it only appears to show solver sessions (and some of our users don't click Solve). For context, trying to find a robust way to identify AIMMS PRO user accounts that are no longer used

Understanding Latency and Bandwidth in AIMMS Cloud Applications & SC Navigator

Customers and users frequently bring up ‘latency’ and ‘bandwidth’ effects when using our Cloud SaaS.This post is intended to provide clarity around this topic based on what we hear from customers using the AIMMS Cloud Platform or SC Navigator.First, what are we talking about?DefinitionsLatency refers to the delay or lag between when a user performs an action and when they receive a response from the application. It is influenced by factors such as the physical distance between the user and the server, the network infrastructure, and the speed of data transmission. Higher latency can result in slower response times and can be frustrating for users, especially when real-time analytics or time-sensitive decisions are involved. Bandwidth, on the other hand, refers to the amount of data that can be transmitted within a given timeframe, the data transfer speed. It is measured in bits per second (bps) or megabits per second (Mbps). Bandwidth determines how quickly data can be sent or received

Building a business case for moving from PRO On-Premise to PRO Cloud SaaSBlog

Based on an exercise we conducted with a specific customer recently, we would like to offer a framework for building a potential business case for making the switch from PRO On-Premise to PRO Cloud SaaS.Historic contextIn 2011 AIMMS launched AIMMS PRO, a deployment platform for AIMMS applications. It ran on servers inside our customers’ data centers or cloud tenants.It met customers’ needs for:Easily and quickly distributing AIMMS apps to end-users. Lower Total-Cost-of-Ownership (TCO).In 2016 AIMMS launched the AIMMS Cloud SaaS, delivering AIMMS PRO as on-demand cloud-powered Software-as-a-Service. In addition to the needs listed above, it met customers’ needs for:Security, reliability and scalability Not having to ‘manage IT’After that, all new AIMMS customers opted for this new SaaS solution, the AIMMS Cloud SaaS.Because of this customer preference and because almost all companies now have a ‘cloud-first’ policy, AIMMS made the strategic choice in 2022 to focus innovation on the AIMM

Repeated "Busy" Message with multiple users on AIMMS Pro

Hello AIMMS Community,My team has encountered an unusual issue on an app released on AIMMS Cloud. This issue is only seen when there are multiple users accessing the application. What is the error? When two users access the application, a “Busy” status is displayed every 3-5 seconds for both users and the app is frozen. This “Busy” displays even when the users are NOT changing anything and starts as soon as the second user’s app finishes starting up. The app has no issue with a single user. Clues to causes of the error? We have narrowed down the line of code that we introduced that causes this issue. “Empty sCoreDataIssues;”. sCoreDataIssues, a set, is assigned to a CDM category. This line is within a procedure “prCoreDataCheckForIssues”. This procedure is called in a number of “UponChange” procedures (called in webui::UponChangeProcedure). Our feeling is that some parameter or set is changing continuously, the upon change is being called, and the “prCoreDataCheckForIssues”, with a non

What is your 'BI platform' and how to do feed it data?

To help us develop relevant data integration support we would like to ask you a few questions about your ‘BI platform’ (PowerBI, Tableau, etc and the data storage for 'feeding’ it):Do you want to visualize or analyze AIMMS data in your this BI platform? Which BI platform do you use (PowerBI, Tableau, etc.)? What data storage technology is used for ‘feeding’ your BI platform? Examples: SQL Server database, Snowflake, Databricks, file storage, etc. What mechanisms and processes are in place to retrieve data from other systems into this data platform? Is it done automatically or manually triggered? How often is data retrieved? Any quality controls in place? Etcetera.Really curious to hear from you.Thanks.

Azure Data Lake Storage for AIMMS Cloud: how to find Storage Access Key

Dear all, I was very happy to see that an ADLS has been added for every AIMMS Cloud account. We would like to use this, and have found that it works well on the Cloud, however we cannot get it to work locally (from a local AIMMS Developer environment): it looks like we need the Storage Access Key for the ADLS, but I haven’t been able to figure out where to find/access this. Could anyone help us out? Thanks!Meike

Recognizing failed jobs in your app

A job (an AIMMS PRO solver session) may fail, for instance because it ran out of time, ran out of memory, or for some other reason.As an end-user, you can see which jobs failed in the AIMMS PRO portal. But not all end-users know this or remember to check this.As a developer, therefore, you may want to notify yourself, or your end-user(s), of failed jobs, such that appropriate action can be taken timely.Please find enclosed an example of an AIMMS app, whereby the solver session will run out of time after a minute. Its user interface looks like: The UI of the app "fail” that illustrates how to capture failed sessions.In the upper half of this UI the failed jobs of last week are shown. Essential here is a call to the procedure pro::sessionmanager::ListSessionSinceDate and listing only the jobs with a status >= 7 (failures).In the bottom half job that was launched using button "buttonFail” is shown. To the right, the sp_status is filled in he procedure ServerErrorCallback, which is inst

Global error handler doesn't work in delegated server session

Hi,I have a procedure that I run with pro::DelegateToServer. When I run this procedure in an end-user session on the cloud, the global error handler runs fine when it comes across this statement:raise error "artificial error";.I have set the global error handler in the option menu: However, when running the same procedure in a delegated server session, the global error hander doesn't run. As workaround, I now included this onError block in my code, but it feels a bit weird to me that this is required to trigger the global error handler.  Is this expected behavior? I'm running AIMMS 4.97 on the Cloud.

Now available in AIMMS Cloud: Azure Data Lake Storage Gen2Blog

Did you know that every AIMMS Cloud account is by default equipped with an Azure Data Lake Storage Gen2 (ADLS). You can use this storage account to store all types of files that you want to integrate with your AIMMS application. You can also use it to store files generated based on the output of your optimizations, as to make them available to an external source.We’ve posted a how-to about this new DataLake toolkit now in place!The Data Exchange Library offers functions to easily interact with the ADLS.This toolkit offers you the possibility to easily create a SAS token which is needed for authentication if you want to access the ADLS from an external source. It also allows you to fetch and manage the currently known file systems (‘containers’) on the ADLS and the paths (folders) and files in it.Come and see! 😀

How to view central storage as regular pro user

Hello! We are working on a project where data files are stored in central storage following an optimization. We would like users to be able to view and load those case files into a session at a later point in time. We store these data files in a PublicData folder for all users to use. However, regular users are not able to see any of the folders/items, no matter what the permissions of a file/folder are. Am I missing something regarding how central storage viewing works?  Looking forward to your answer!

Time limit for AIMMS PRO Jobs

Recently, someone asked me about time limits for AIMMS PRO Jobs.You can control the timeout via the timeout argument in pro::delegateToServer. Note that this timeout is in milliseconds.When thinking about time limits, I usually think about time limit for the solver.To provide the solver with the opportunity to share the best solution thus far, I usually add some minutes to cater for case load, project start, case save etc of the job to the time limit for the AIMMS PRO Job.  Therefore, my delegate sometimes looks as follows:if pro::DelegateToServer(       ...      timeout: p_timeLimit * 1.2 * 1000 + 5 * 60 * 1000, ! timelimit for job is in milli seconds.      ....) Where p_timeLimit is the time limit in seconds for the solve itself.
