Abstract: As the bottlenecks part of the material support supply chain, wartime logistics center’s distribution capability and risk are the key factors for decision. Nevertheless, the complicated and uncertain service process makes it difficult to fully, accurately, intuitively analyze. The system simulation method is adapted to describe wartime military logistics. In view of the risk, queueing Petri nets is extended and used to model the technological process of logistics center. Finally, QPME tool is used to simulate the center model. Based on simulation data, the performances of logistics center are analyzed by varying the settings. The value of distribution capability and risk is calculated to make decision. The simulation results show that this method can help relieve bottlenecks and make decision, in addition to analyze the capability and risk of logistics center.
