Abstract

Warehouse design is a complex problem. It involves decisions regarding the warehouse processes, resources, and organizations. Real-world systems are challenging due to their size and because they are subject to uncertain and dynamic conditions. The outcomes of random events cannot be predicted with certainty. However, if random events are studied and repeated sufficiently frequently under identical conditions, stochastic or statistical regularities can be found. There exists a research gap on the combination of optimization with discrete event simulation. This research gap is the main problem addressed in the project. A warehouse problem identified by Wijnne Barends Logistics is used as real-world business case throughout the project. An product allocation optimization model is constructed in order to fit the business case. Multiple types of layouts are calculated and the most optimal one with almost 9,3% time and 8,8% queue reduction has been used for further simulations. A digital twin is created in Anylogic where the optimal layout is subjected to stochasticity in the incoming and outgoing orders. The model showed robustness towards the stochasticity based on the observed results and provided managerial insights for Wijnne Barends Logistics.
