AIMMS PRO On-Premise & AIMMS Cloud

Are all solvers supported on the AIMMS PRO on-prem platform supported on AIMMS Cloud? If not, what are the current list of solvers supported?

Imagine this scenario:Your organization asks you to develop a large-scale, business-critical application that enables dozens of users to interact with optimization models in real time through a modern web interface.At first glance, it sounds straightforward. In reality, it requires a complex technology stack and significant engineering effort. Here’s what that entails:What You’ll NeedA scalable API layer (e.g., FastAPI; Flask is an option but less suited for large-scale systems) A distributed job queue (Celery with Redis or similar) A solver cluster (Gurobi, CPLEX, OR-Tools—each with its own integration challenges) A Kubernetes deployment for orchestration and scalability Event-driven WebSocket architecture for real-time updates Authentication, authorization, data versioning, rollba

Hello,My name is Stephen Pursey, Supply Chain Optimization Analyst at Airgas / Air Liquide. We currently use two AIMMS-based applications: ORTEC’s OSCD and an in-house tool. Both appear to share the same limitation, which I believe may be at the AIMMS platform level.In our supply chain model, each customer can have one or more “mandatory” sources from which they must receive product. However, AIMMS seems to only recognize up to two mandatory sources per customer; any additional mandatory sources are ignored. This creates practical constraints in accurately modeling our network and weakens the quality of the optimization results.Could you please let me know:Is this a known limitation of AIMMS?If so, is there a recommended workaround or configuration change?If not, could we work together to identify the root cause and potential fix?We rely heavily on AIMMS for critical production and distribution decisions, so resolving this would have

AIMMS Applications deployed on AIMMS Cloud are designed to be End-User friendly. Still incidents may occur, and then it is useful to have logging information available such that post mortem analysis can go quickly to the cause of the incident at hand. Suggested project option settings:Option 1: communicate_warnings_to_end_usersWarnings can provide useful information, typically to developers of the application and to maintainers of the data sources (warnings on inconsistency of the data). However, not all end-users are familiar with the design of the application at hand, and may therefor be unnecessarily rattled by these messages.For the above reasons, the default of the option communicate_warnings_to_end_users is off.However, best practice is to turn these warnings on, provided there is error handling in the application, such that warnings are logged and handled, but not shown to end-users.

Hi,I am wondering whether it is possible to read the Jobs screen data from the PRO server into an AIMMS project. I am especially interested in the Process ID but would like to read all the information if possible. See below.Best,Gorkem

Dear Community,I wanted to share an example for which you can monitor if the user has been idle in AIMMS for a certain period.Why?You may want to check if your users are not leaving applications open while not using it for long periods , effectively occupying user licenses and compute power while blocking other users.There already is a timeout for WebUI applications, but this only happens if the browser tab is closed, is made idle by the browser, or the connection is lost - hence, if the user opens the app but simply forgets it open, it will not be automatically ended.How?To do this, I have two simple procedures:Procedure pr_checkIdle { Body: { if DataChangeMonitorHasChanged("idle_monitor") then sp_log += CurrentToString("%c%y-%m-%d %H:%M:%S") + " DataChangeMonitorHasChanged detected change\n"; DataChangeMonitorReset("idle_monitor",s_identifierToMonitor);

We are working on a redesign and rebuid of the Jobs page in AIMMS Cloud. Can we have your input on a few topics?What are you using the Jobs page for? What changes and improvements would you like to see there?  What existing features would you like to see moved from other parts of the AIMMS Cloud portal to the Jobs page?We are looking forward to your input!

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 Stat

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:  

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)

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?

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)

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

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

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 involv

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.Be

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 be

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. 

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

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

Dear All,  As you have probably read in one of our e-mails we are excited to announce that new versions of AIMMS and AIMMS PRO are coming up.With the release of the new AIMMS version, our AIMMS libraries will undergo an update. To continue benefiting from the latest library enhancements, it is crucial to update your AIMMS version to 24. Please note that the new libraries will only be compatible with the 24 AIMMS version and vice versa.To enjoy the new features of AIMMS, an update to your AIMMS PRO version is necessary to a PRO 24 version. The previous AIMMS versions will still operate smoothly on the new AIMMS PRO 24. Please find a VERSION COMPATIBILITY TABLE below:   AIMMS 4 AIMMS 24

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. 

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 curren

Hi All! I have read the documentations but I haven’t find the detailed answer I would need. How can I access and restore AIMMS Pro backup? Is there any special process for it in AIMMS Pro? Thank you in advance!
