Benchmarking Optimization Tools for Scale: AIMMS vs. Pyomo & JuMP

Benchmarking Optimization Tools for Scale: AIMMS vs. Pyomo & JuMPLarge-scale optimization plays a vital role in solving complex problems across industries. As models scale in size and complexity, performance becomes critical — especially in enterprise settings where fast turnaround is a must.With the release of AIMMS 24.6.1 in late 2024, we introduced a redesigned model generation engine, purpose-built for large-scale use cases. To evaluate its real-world impact, we asked Deanne Zhang to lead a comparative study on performance.The study benchmarks AIMMS against two popular open-source tools — Pyomo (Python) and JuMP (Julia) — using anonymized logistics workforce models featuring 1M+ variables and constraints. It focuses on model generation time and total execution time, offering a practical lens on tool performance at production scale.The results are insightful — and relevant for anyone navigating large, mission-critical optimization workflows.Read it on Medium

As an expert in supply chain optimization, she’s known for making complex models transparent and accessible to both users and consultants. Through her platform Optimization4all and engaging content across channels, Cristina is building a community that bridges the gap between theory and practice.In this interview, she shares her journey, insights, and passion for bringing clarity to the black box of optimization.How do you introduce yourself to a potential new client?I am a supply chain optimization expert. I design and build tools using mathematical optimization. These tools are often seen as a black box. I open that box and bring clarity and trust—ensuring the tools effectively support planning processes.If someone at a pub asks what you do, how do you explain it?I’m a mathematician. I write the equations companies use to optimize their manufacturing and distribution flows.How would you explain to a passerby that

New AIMMS Feature: End-Users Can Identify Incorrect Data in Case of Infeasibility

SummaryThis new feature addresses the infeasibility problem caused by data. The key function is to generate insightful messages for the end-users as well as additional information which may be used in the WebUI. The app developers can embed this feature in an application by setting the main function to run behind an action in the WebUI and by using parameter annotations to highlight suspicious data.What problem is addressedIn mathematical optimization, even the models which are correctly formulated can face the challenge of infeasibility caused by incorrect input data. For app developers, AIMMS offers already for a long-time several effective tools for dealing with the model infeasibility. However, for end-users, this situation could lead until recently to frustration and uncertainty, with questions like, “Why is the model infeasible?” and “What is wrong with my input data?”What does the new feature do To address this problem, AIMMS introduces a new feature which may be used by the app

Webinar: "Dealing with Infeasibility Caused by User-Provided Input Data"

When:Monday - December 16, 2024  15:00 PM - 16:00 PM CET09:00 AM - 10:00 AM EST  19:30 PM - 20:30 PM IST Speaker:Marcel Hunting, Algorithmic Capabilities, AIMMS Introduction:In optimization, even the most meticulously designed models can become infeasible - not because of errors in formulation, but due to incorrect or unrealistic input data provided by end-users. This can lead to frustration and confusion when users ask, “Why doesn’t this work?” and expect some explanation as well as actionable insights to correct the problem.This webinar introduces a powerful new feature in AIMMS which tackles the challenge of diagnosing and resolving infeasibility caused by incorrect input data. The focus is on empowering end-users to identify and correct problematic data in a systematic, user-friendly manner, ensuring their optimization models achieve feasible solutions efficiently.Through this new AIMMS function, users can:Detect the root causes of infeasibility: By calculating Irreducible Inconsis

Get notified when new releases are made

A customer asked us how to keep up to date with releases in AIMMS. We used to send out emails when a new version was released (many years ago), but the frequency is much higher now and felt it would be unhelpful.If you do have an interest in following releases, I have tested out a site (visualping) that can monitor and notify you when there are changes to a site.To be clear, AIMMS (and me personally) have no affiliation with this site - it just seems useful.https://visualping.io/You can add an html and select which part of the site it should compare. If there are changes in that part - you get an email. Simple as that.Here is an example:  Free tier allows you to monitor 5 sites - so it can cover AIMMS, PRO, WebUI and two of your favorite libraries. Most actively updated library is DEX.In case you don't have a link to the release notes handy, here they are:https://documentation.aimms.com/release-notes.htmlhttps://documentation.aimms.com/pro-release-notes.htmlhttps://documentation.aimms.

Insights on how we implemented a data monitoring system at AIMMSBlog

This post shares our challenges and insights of working with data from various sources as a data team at AIMMS. We used Great Expectations to power our data monitoring system. With this system we identified data quality issues and prevented unexpected results in our analysis. Most people working in analytics will recognize the following scenario: you need to perform analysis on data which are generated or produced by other teams. Because you are a consumer of the data source and are not managing the data source itself, you need to investigate the data source to learn if the analysis can be done and how confident you can be of the results. However, this is not enough since data can change, and such a change can have a huge impact on the results you are delivering as an analytics team. The data challenge at AIMMSAs a data team at AIMMS we are tasked with creating insights based on the data we collect at AIMMS. This means combining different data sources and performing all kinds of analys

What's new in Algorithmic Capabilities?

What's new in Algorithmic Capabilities? We keep close eyes on algorithms for optimization, and do our best to bring in new solvers that can benefit AIMMS users. When a new solver arrives on the market, we have a vetting process to see how it compares to those already offered with AIMMS. Additionally, we take into consideration our users' specific needs.Read on to find out more about this process, especially as we added two new solvers last year: Octeract and COPT.  Testing and evaluating Modern linear solvers can read and write MPS files which is a standard file format for presenting linear models. We have a large collection of MPS files which we use to evaluate a new solver using an automated process. This way we can test a linear solver with minimal effort -- we do not have to first create a link with AIMMS. Once we run the solver on our benchmarks of MPS files, we can compare its performance with other solvers. To evaluate a nonlinear solver we have to create a link with AIMMS first

(SOLVED) August 30 2022 - AIMMS Cloud Platform on Azure down

12.37hrs (Amsterdam time) - The Azure version of the AIMMS Cloud Platform is down, because a key Azure service is down (compute nodes), most likely because of an operating system (Ubuntu) upgrade. Microsoft and Ubuntu teams are working on resolving the issue. We are expecting another update from Microsoft in the next hours. We will keep you posted.

AIMMS 4.88 - AIMMS PRO 2.44 (on-premise installation)

This or next week, AIMMS 4.88 will be released (our goal is a September 1-release).You are receiving this email because you (or one of your customers) are using an on-premise installation of AIMMS PRO to deploy AIMMS applications. For applications that are or will be built with AIMMS 4.88 (or future versions) to be published on PRO, it is necessary to update AIMMS PRO (on-premise) to version 2.44, released July 15. https://documentation.aimms.com/pro-release-notes.html It might also affect some Repository Libraries, but that will be solved 'automatically' when you open the model in AIMMS 4.88 (or future versions).If you open the model in AIMMS 4.88 (or future versions) before publishing, the Autolib will find the supported version for all repository libraries in the model and will show a pop-up that versions have been updated, and you need to save the model. Only when the model used a very old version ( <1.0.0) of the Unit Test Library, some incompatibility may arise because an iden

WebUI Insights with Pratap Kumble

Many of us in the online community know @Pratap Kumble, who has been our WebUI product owner for several years. Pratap is based in Bangalore, India and is part of the team at DevOn, one of our software development partners. Pratap is leaving the WebUI team later this month and moving to Germany to take up a new role. He will be succeeded by @Madhu Krishnappa, whom many of our community members also know. But we didn’t want to say goodbye without hearing more about his tenure at AIMMS.  How would you describe working with AIMMS?  It’s been a very different experience for me. With AIMMS, we were given a lot of trust and freedom to do what we think is best. AIMMS is also not a typical software company. Generally, in software development, you develop an application for users. When it comes to AIMMS, your user base is completely different. You are developing a product for modelers to build applications. This means you have 2 audiences: end users and modelers. This makes it an interesting so

New Execution Efficiency Master Course on AIMMS AcademyNews

Are you looking to improve the execution efficiency and overall performance of your AIMMS apps? Then this new master course is for you! As you know, your model computes:  the coefficients used in the mathematical program, and  the values shown in an end-user interface after solving a mathematical program. The way these computations are formulated in your model impacts its overall performance. This course consists of two pillars:  A theoretical pillar that explains how AIMMS’ data structures are designed and how sparsity in data is used in computations.  A practical pillar where you change code in hands-on exercises to improve execution efficiency. You'll find, in some cases, that a different formulation can be a hundred times faster.  Enroll today! For questions, please connect with @Chris Kuip, the course’s creator.
