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.
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

Hey community! Hope everyone is doing fine! I come with great news! We are on the process of updating the AIMMS examples, from the app itseft (development/features) to more detailed information on the How-to page. Main changes are:How-to now will have standard topics such as: Story Mathematical Model Language WebUI Features UI Styling Minimal Requirements Each page will have 3 shields: One with the Github ZIP link One with the Github repository link One indicating if the example is on WebUI or WinUI Main Example github repo is going to slowlly be disagreggated. Each example/AIMMS project will have their own github repository. Remember that you can fork any repository from our Github! The first example updated was the Contract Allocation! It is ready for you to look around and learn from it!
AIMMS Academy has added a new course in the Foundations series!Foundations 201: Data modeling for linear programmingThis course covers how to solve LP problems with the model and data separated.This approach allows you to:Keep the structure of the model invariant. Provide flexibility so that changes in the data are easily handled. In this course, the distribution problem of "Foundations 101: Introduction to Linear Programming" is extended in two steps:First, the model is extended to deliver pallets of bottled water to more destinations. Second, the model is extended with multiple bottling locations.The goals of this training include:Learn the notation to separate model and data. Use AIMMS Developer to read data and solve the problem. Present tables containing both the data and the solution in the WebUI.Head to the AIMMS Academy to sign up now!

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
AIMMS’ purpose is to help organizations make confident decisions, powered by mathematical optimization, for a more sustainable world.

Contribute to our forest and help us reach our goal!Are you certified in our one our courses? Share your AIMMS Academy course certificate on social media using the hashtag #AIMMSAcademy. Send us a link to your social post. We will plant a tree in your name.Join the tree planting campaign or leave a comment below if you have any questions!
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.

Dear Community,I’m pleased to announce that as of April 1, I have turned over my leadership roles at AIMMS to a team of experienced colleagues with whom I have been closely working together for many years. As non-executive board member and shareholder, I will continue to steward AIMMS towards expressing our purpose, living our values, and unleashing our full potential. Last October, I shared my intention to hand-off my leadership roles. As a follow-up, a group of experienced AIMMSians ran a project to determine the best way forward, ensuring continuity and a seamless transition.The team that is taking over my roles is more than ready to do so. Many of you have known them for quite some time. Key strategy and product roles are led by Gertjan de Lange and Marcel Roelofs. Patrick Donders is responsible for Customer Success. Sergi Asensi leads new Customer and Partner Acquisition. Laura van Dijken oversees Marketing and Communications. Pauline Nobel heads up HR. Jan-Willem van Crevel is ta
Not many people know that several electricity markets in Asia have been modeled and optimized using AIMMS. This includes some of the largest state grids in the region. When we heard that Oliver Nunn, a leading consultant in this area and an AIMMS power user, was starting his own business, we could sense the start of a great partnership. @LauraV recently spoke with Oliver about his journey with AIMMS and the services he provides for organizations in the industry.Oliver, can you tell us a little about your background?I’ve worked as a consultant and advisor in the Australian energy sector for the last 11 years. During that time, I have provided advice on a wide range of optimization projects, including modeling of outcomes in the Australian national electricity market, the Philippines power market, and the Vietnam power system. I hold a first-class honours degree in pure mathematics, and a commerce degree with majors in economics and finance.What brought you to this field and how did you

We are happy to announce that a new Error Handling course is now available on AIMMS AcademyIn software development, errors inevitably occur. Whether it’s typos during interaction, erroneous input, coding errors, or externally caused issues, such as a broken internet connection. Did you know AIMMS has built-in features that allow you to diagnose and handle errors? The course teaches you to use these features, so you can provide easy-to-use applications for end users. Sometimes, just knowing how to communicate the error can reduce a lot of friction in an app. Applications with extensive diagnostics and careful and consistent error handling make users feel in control.Sign up for the course and follow it at your convenience. If you have questions about the training, feel free to contact its creator, @Chris Kuip.

Are you thinking of contracting a partner for your AIMMS development project or outsourcing a new IT initiative in your company? Many organizations contract external partners who often act as an extension of their team. We recently spoke with Madhu Krishnappa, Senior Test Specialist and Agile Practitioner at DevOn, to get his tips on what makes outsourcing and co-sourcing successful.Madhu has worked in agile software development for close to 15 years and has been working with AIMMS for 3 of those years, helping us accelerate the development of our GUI builder and WebUI features.Madhu, outsourcing generally involves a great deal of trust between both parties and building that trust is not always easy at the beginning. How do you do it?It all starts with creating a joint understanding. Your outsourcing partner should understand your vision – that is, why you need their help, what you are looking for and where you want to go. It’s key to explain your problem statement clearly. At DevOn, w

Include maintenance and after care in your planning This article is part of the series “Set your project up for success.” Even after an app is accepted, know that there will be a life cycle. Along the way, your app will likely need to "mature" and be adapted. Making a plan for maintenance ahead of time will set expectations for everyone involved. Know that there will be a life cycle. Your app will need to "mature" and be adapted. Entering the maintenance and support phase After the application is delivered and accepted by users, the project is usually closed and a new phase starts in which users will find bugs, ask questions about usage, and request new functionality. We recommend entering into a maintenance and support contract with the customer for this. Do not forget to include the costs for testing in your contract. Be specific about how the users' needs will be met: Bug reports - How quickly will these be dealt with? How will they be prioritized? Usage questions - How will they c
Students from the University of Luxembourg were trained last week in the use of AIMMS Network Design. The 3-hour training session hosted by university faculty members for a Logistics Management course, and conducted by myself and Paul van Nierop, helped students feel comfortable with using Network Design and Center of Gravity. They will be using these SC Navigator Apps to perform a case study project with the objective of designing an optimal Network for a fictional distribution company (“DistriLux”) and prescribing new, creative solutions to the business.A virtual hands-on zoom training was conducted with 21 Master students joining from all around the world. The feedback was very positive from both the professors and the students. Personally, it was a great experience for me to engage with students from the same Master's program I graduated from in 2019. I feel confident that they will begin to see the value of our apps as they get deeper into it over the next 10 days.Photo by Prof. A
Managing organizational change as part of implementation This article is part of the series “Set your project up for success.”The implementation of a new software product actually always implies a change:An old tool is replaced New functionality is added, old, perhaps much-loved, functionality is removed Tricks and workarounds might no longer work A new UI, a different workflowBut often the change goes further than end-users who get a new app:A new process is implemented Data streams are merged Departments must collaborate or become dependent on each other Figures that were only known to a few are made explicitThese are all examples that we have encountered during AIMMS projects over the years. If properly handled, a project can be successful. When they're not, a project can be endlessly delayed or even fail.In this post, you will not find golden rules for Change Management. Instead, we'll share a simple advice: Realize, at all times, that a project with AIMMS brings about a change and
An interview with UX Designer Thomas Pleeging AIMMS takes pride in providing a great user experience, both in SC Navigator applications and through our WebUI, which provides a toolkit for AIMMS developers to deliver a great-looking user interface in their Apps. Often, translating our supply chain expertise into a great UX does not come easy, especially in robust apps that have multiple types of functional users. To ensure we have a user-centric approach, we work with user experience experts. We spoke with Thomas Pleeging, former UX and Senior Designer at Total Design, to get his take on this UX improvement journey and uncover some of the highlights. Thomas, as an agency, how do you ease the collaboration between the business (supply chain) side, design and development? Our standard way of working starts with a session. So, we organize a session with the product owner (who typically brings the business or supply chain expertise), the developers (who know about data modeling and t
