A modular discrete-event simulation model for a miniload-workstation (ML-WS) order picking system has been developed using a process algebra based simulation language. The proposed model is structured systematically such that distinctions between areas and operational layers can be clearly identified. Furthermore, subsystems and decentralized controls are applied in the model architecture. We demonstrate the modularity of the model by experiments, in which some control heuristics and the number of miniloads are altered. A realistic, industrial scale distribution center is used as the reference case for the simulation study. The resulting model architecture allows easy implementation of various system structures, design parameters, and control heuristics.
