Abstract
Purpose – The purpose of this paper is to present an analysis of how different sourcing policies and resource usage affect the operational performance dynamics of warehouse processes. Design/methodology/approach – The system dynamics (SD) methodology is used to model warehouse operations at the distribution centre of a leading fast-fashion vertical retailer. This case study includes a detailed analysis of the relationships between the flow of items through the warehouse, the assignment of staff, the inventory management policy, and the order processing tasks. Findings – Case scenario simulations are provided to define warehouse policies enabling increased efficiency, cost savings, reduced inventory, and shorter lead-times. Practical implications – The case study reaffirms that a flexible usage of human resources, outsourcing of selected warehouse operations, and sourcing from reliable manufacturers may result in important performance improvements for centralised warehousing. Originality/value – It is proved that SD is a valuable tool in the field of operations management, not only to support strategic evaluations but also to execute a detailed analysis of logistical processes and make scenario-based dynamic decisions at the operational level.

1. Introduction The increasing need to improve supply chain (SC) performance has been forcing warehouses to focus on integrating the production effort with the market (Frazelle, 2002; Baker, 2007). Receiving, transferring, handling, storage, packing, and expediting operations at the warehouse directly affect the effectiveness of a company as a whole as well as its quality and logistic service level (Rafele, 2004). In this sense, a proper warehouse
