The placement of safety stock is managed as an experimental variable within the initialisation process. In upstream safety-stock scenarios, supplementary safety stock is allocated to warehouse-level nodes, including the central warehouse and secondary warehouses. In downstream safety stock scenarios, the supplementary safety stock is allocated to retailer-level nodes. This framework allows the model to evaluate both policy type and the impact of stock positioning within the multi-echelon distribution network.
