Simulation modeling is a powerful method for designing, planning, and optimizing warehouse operations. By creating a digital twin of a warehouse, companies can design, simulate, and test within current and new warehouse operations, including (semi) automatic order picking, batching algorithms, stock allocation, (empty) tote management, tracking and tracing temporary storage, and shelving virtually.

The challenge is to achieve the most efficient warehouse operation. Simulation modeling can contribute to the selection of the best order-picking module, conveyor and sorting systems, or automated storage and retrieval systems (ASRS). Using simulation software, warehouse managers can easily plan during peak days and determine when these peak moments are. By integrating the Warehouse Management System (WMS) with the simulation model, data from the inventory can be used for accurate simulation studies.

Questions that can be easily answered using Simulation Software are:

• How to deal with capacity shortages both in operation and in design?
• How many extra Shifts and/or resources are required?
• How much surplus capacity do you accept during the rest of the year to handle your peak day? E.g. Do you leave an entire floor empty for a whole year, which you then only use during your peak period? How and when to fill up this floor. What measures to take to ensure sufficient stock?
• What do you do if a part of your system breaks down (contingency)?
• What are the lead times and are they short and stable enough to ensure product safety in case of, e.g., chilled foods?
• What is the reason to implement a shuttle system and robots.
• How to optimize your and 3^rd Party equipment, staff and logistics?

From an emulation perspective, managers can get insight into the operation. How is the performance on a peak day/period? What extra dynamics do peak days provide? For example, during special offers on black Friday, there might be flows that would normally never be seen. How to cope with these challenges?

Enterprise Dynamics® is a powerful and robust simulation platform that provides a digital environment where you can safely explore a solution without impacting day-to-day operations. By using a virtual model to validate and visualize current and future operations, optimizations and innovations will demand less costs, risks, effort and time. So, supporting maximal operational performance.
