Dear all, I write on behalf of baobab soluciones, an AIMMS partner based in Madrid. Since the onset of the pandemics we have decided to support organizations and public authorities and offer our solution development services pro-bono for crisis relief projects. We were thinking route optimisation, workforce optimisation, workload management, load balancing between centres, for healthcare, quick response and critical supply chains. Quick, technically simple projects that will help take the most out of our exhausted common resources. So if you encounter a situation where we can be of assistance, please do not hesitate to contact us. Thank you very much, Julio
Immediate Supply Chain Actions to Take Amid COVID-19Knowledge Base
There are many impacts of COVID-19 that will be felt by Supply Chains in the coming weeks and months. As advised by McKinsey, in the next 2-4 weeks it is critical for companies to understand the exposure throughout their value chain, take actions to address anticipated shortages and ensure resources requirements to restart. Supply chain planning tools like AIMMS SC Navigator can be used to directly address many of these impacts and help businesses recover quickly from losses. We hope that this series of articles gives you some direction - and we welcome your comments and advice from experiences relating to these challenges. Understand Exposure Study 1: Anticipate Best- and Worst-Case Operations Scenarios Study 2: Inspect Demand Trends Anticipate Shortages Study 3: Identify Optimal Sourcing Locations Ensure Resource Requirements Study 4: Create Multiple Plans for Resource Utilization Study 5: Refine Capacity Smoothing Study 6: Accelerate Adoption of Relevant Customer Channels
Many organizations now struggle with the task of sourcing and allocating COVID vaccines within their regions.We’ve recently published an interview with Theo Goutier of the Netherlands Municipal Health Services. Goutier, who has led Vaccine Program Operations, tells how they provided vaccinations to those who needed it most while dealing with fluctuating supply and demand, among many other complexities, and what insights they gained from the project.They used an AIMMS-based tool created by our partners at Quomare to:Compute what-if scenarios Determine the optimal number and location of vaccination stations Generate a ‘demand forecast’ for each location Balance required capacity per location, versus expected demand distribution over timeRead details of this case on our Blog: Increasing Speed and Efficiency of Vaccine Distribution During UncertaintyFollowing the success of this tool, a version of such a vaccine-planning application is now available for non-profit use through Math4Good, an
Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It helps in the fight against climate change by trying to reduce the CO2 levels in our atmosphere. Popular techniques for carbon sequestration are reforestation and afforestation. They are both similar but slightly different: Reforestation is restoring forests on lands that were once forests but are no longer, because of deforestation for farming, commercial activities etc. Afforestation is creating forests on lands that were not previously forests. This could be repurposing land that was used for farming, or mining etc. into forest land. We at AIMMS have started a new program, AIMMS Forest, to contribute to the fight against climate change.We have partnered with One Tree Planted to support reforestation projects around the world and would like to invite you to join us by participating in this fun challenge. For every person that solves the challenge using an AIMMS model, we will plant 20 trees
We have had the pleasure of interviewing many academics about their use of AIMMS. Often, they are working on innovative research projects that will shape the future of our economy for years to come. Edwin Zondervan is one of them. Edwin is a professor of process systems engineering at Twente University and has been using AIMMS for several years. His work focuses on the energy transition and topics surrounding the hydrogen economy, biobased production, carbon capture and utilization, and electrochemical energy storage. We were curious about how he applies AIMMS in these areas. Can you tell us a little bit about yourself and your background? How did your interest in optimization and modeling develop? I was born and raised in Leeuwarden, Friesland – in the north of the Netherlands. I got a bachelor’s degree in chemical engineering with a specialization in process automation. This is where my interest in mathematics and chemical engineering was born. I continued with a master's in chemica

Supporting the Dutch Healthcare System with AIMMS-based Optimization During the COVID-19 PandemicBlog
This article is based on an interview with Erwin Hans, Professor of Operations Management in Healthcare at the University of Twente and Co-Founder of CHOIR and Rhythm B.V. Erwin is helping care givers address the challenge of critical care capacity and is looking for motivated students with AIMMS know-how to join the effort! AIMMS and I have a long-standing relationship. As a former student of applied mathematics at the University of Twente, an institution where I now teach, I completed my graduation project under the supervision of AIMMS’ founder, Johannes Bisschop. Jan, as we call him, was my thesis supervisor. My path in OR started at the Energy Research Foundation in the late 90s. During my time here, I conducted my master’s research on the liberalization of the European electricity market. Specifically, I developed an AIMMS-based model to understand how electricity transport, post liberalization, would impact prices. After completing my research, I took on a PhD position in logis
Study 6Knowledge Base
Study 6: Accelerate Adoption of Relevant Customer Channels This study can help you ensure resource requirements in your supply chain. Impact – A very likely scenario is an accelerated adoption of certain customer channels, for instance online grocery. These channels might not be able to bear the increased shift in demand. Action – Relevant customer channels must be prioritized and the resource requirements to fulfill their demand must be studied. How –AIMMS S&OP Navigator allows users to prioritize their customers to increase the fulfillment in that channel. Although a forced higher fulfillment of one channel might lead to an overall lower margin, understanding the impact on your resources of putting a higher burden on that channel could prove to be invaluable in the long run. Demo –Customer Channel Priority in S&OP Navigator This article is part of the series Immediate Supply Chain Actions to Take Amid COVID-19.
Study 5Knowledge Base
Study 5: Refine Capacity Smoothing This study can help you ensure resource requirements in your supply chain. Impact – As certain resources are forced to close, other resources will experience an increased load. Companies may not be able to adequately ramp up capacity and lose sales. Action – Inventory must be kept in anticipation of resource unavailability in the future. At the same time, over-utilization must be reduced to not exhaust the resources. How –AIMMS S&OP Navigator enables users to perform capacity smoothing. This incurs a penalty on over-utilization and tries to minimize it by ensuring that inventory has been built up in anticipation of future shortages. It also suggests alternative distribution options for obtaining the product in case the resource in question is unavailable. Demo –Capacity Smoothing in S&OP Navigator This article is part of the series Immediate Supply Chain Actions to Take Amid COVID-19.
Study 4Knowledge Base
Study 4: Create Multiple Plans for Resource Utilization This study can help you ensure resource requirements in your supply chain. Impact –Manufacturing plants and warehouses will experience a sudden shift in resource utilization. There will most likely be a reduction in labor hours as fewer people will work in a closed, crowded environments. This could even lead to total shutdown of certain plants. Action – Study multiple resource utilization what-if scenarios and accommodate your production plan accordingly. How – S&OP Navigator allows users to simulate changes in resource capacity, labor hours, utilization, production lines and throughput rate dynamically within the application. The output is a detailed production and distribution plan that maximizes your margin. Note:If using your own bespoke app, another option is to re-adjust your objective function. We have seen this work very well in the past where a customer, during a crisis, moved from Production Maximization to Cost Min
Study 3Knowledge Base
Study 3: Identify Optimal Sourcing Locations This study can help you anticipate shortages in your supply chain. Impact – As transportation lanes become unavailable, the availability of suppliers and components will decrease. Action – There is a strategic incentive in understanding the optimal sourcing location for specific customers, and in understanding the optimal sourcing location for the different resources. This is not to say that there is no value in having multiple supplier options, but understanding who your ideal supplier is can enable you to form the right relationship and expectations with them for the coming weeks. How – Network Design Navigator enables forcing a single source as a constraint. Once the constraint is relaxed, customers are free to choose from a multitude of suppliers. However, with the constraint enforced, the optimal source of the product can be studied while minimizing both production and distribution costs. Network Design can also be used to make certai
Study 2Knowledge Base
Study 2: Inspect Demand Trends This study can help you understand exposure in your supply chain. Impact –Since demand will significantly fluctuate and spike for a period of time before reverting to the mean, accurate demand signaling for the future becomes a challenge. Misreading these signals often leads to the bullwhip effect. When shoppers decide to hoard all the toilet paper from the stores, it sends a signal through the supply chain to produce more. If the toilet paper companies decide to produce more, extra inventory is pushed into the distribution channel. Inevitably, demand will stabilize and when it happens, the stores will find themselves overstocked since customers are still exhausting their previous purchases. Action – Demand trends must be studied closely and any outliers must be treated to avoid inaccurate resource planning for the future. How – AIMMS Demand Forecasting Navigator can be used to perform time-series analysis for individual product groups. Machine learning
Study 1Knowledge Base
Study 1: Anticipate Best- and Worst-Case Operations Scenarios This study can help you understand exposure in your supply chain. Impact – Prolonged shutdowns will have both financial and operation implications, which are often very difficult to realize due to the complexity and far-reaching nature of supply chains. Action – Scenario planning is the key to understanding the many repercussions of sudden changes in demand and operations. Multiple best/worst case scenarios should be run under different demand conditions to study its impact on your supply chain. This can help expose any vulnerabilities in the network and take business a step closer towards preparedness. How – AIMMS Network Design Navigator allows users to adjust demand for unique customers, locations and products. This means that you can target very specific parts of your demand data and dynamically run different scenarios in those conditions to measure its effect. On top of this, after demand has been adjusted, demand si
