摘要: 服务备件物流是一个复杂稳定的系统。从系统动力学的角度分析服务备件物流系统,建立了考虑横向调度和纵向紧急运输情况下,包含一个备件中心仓库和两个备件基层仓库组成的系统动力学模型,检验了其合理性。通过仿真得出以下结论:产品停产期前后,服务备件库存波动加剧,是备件库存管理的敏感期;产品生命周期越短、产品使用年限越长,服务备件库存波动越明显,其库存管理难度越大;各基层仓库服务对象越平均,其协作能力越强,服务备件中心仓库储存库存量越少。

Abstract: Service parts logistics is a complex and stable system. From the view of system dynamics, service parts logistics system was analyzed, a system dynamics model containing a central warehouse and two local spare parts warehouses was established, considering lateral transshipment and vertical transshipment emergency, and then the reasonableness was examined. Three conclusions were obtained through simulation analysis. Firstly, volatility of service parts inventory increases before or after the produce idling period, and the period is a sensitive period for spare parts inventory management. Secondly, the shorter product life cycle, the longer product life, which leads to inventory management more difficult, and the more obvious service parts inventory fluctuates. Last, the more average every local warehouse service, the stronger the collaboration capability of every warehouse and the fewer inventory of service parts warehouse.

Key words: service part, Logistics, lateral transshipment, system dynamics, modeling, simulation
