Warehouse assignment model, excl. training

This product comprises a downloadable warehouse assignment model in Python. I named this product “simple” warehouse assignment model because the customer and supplier locations in this model are created randomly. In other, more advanced versions of this model, I made it possible to import real-world customer locations through a csv-file and to visualize these locations on a map. Another…

Warehouse receiving process simulation

A warehouse receiving process simulation study was simulated for bottleneck search and detection, applying the SCDA pallet receival simulator. The simulation study modelled various warehouses with different pallet receival processes and directly impacted warehouse process adjustments, contract management, and capacity-related investment decisions. Exemplary changes and improvements: a) Adjusted…
