Warehouses are essential to the performance of today’s supply-chains. The analysis and optimization of warehouse performance is important to reduce the experienced delay of customers, especially considering the growth in demand fueled by e-commerce. During this three-day workshop various leading experts and young researchers will present their research on the evaluation and optimization of warehouses, using methods, e.g., from combinatorial optimization, queueing theory and machine learning. We plan to discuss both mathematical modeling and analysis, as well as the practical aspect of warehousing design.
