Operations research specialists at the OCP Group, the Mohammed VI Polytechnic University, and the Polytechnique Montreal operationalized a system optimizing OCP's supply chain downstream activities. The system simultaneously schedules production, inventory, and vessels while ensuring the highest demand fulfillment. Therefore, it has become central to the OCP planning process, fundamentally transforming the supply chain and operations management within the group. Planners now use the optimizer's solutions and insights to improve plans. The system was initially a bottleneck curbing the use of other supply chain management tools. However, after its operationalization, OCP management credits the system with providing operational benefits, contributing to over a $240 million increase in annual turnover.
