摘　　要：研究由中央仓库和分布于不同地区零售店组成的多点库存系统,同一地区库存点间允许双向转载,不同地区库存点间仅存在单向转载;库存点面临独立泊松分布需求,采用连续检查的(S-1,S)策略。基于M/G/S/S队列理论、生灭过程模型和近似计算思想,分别建立损失销售情况和延期交货情况下的库存模型。设计了该库存系统的离散事件仿真过程以获取比较标杆。设计了系统参数变化组合实验,对比分析近似模型、仿真模型、策略仿真、单向转载模型和无转载模型的计算结果,发现所提近似混合转载模型的期望总成本最小。A multi-location inventory system composed of a depot and several bases that covers different geographical regions was addressed,where there was bidirectional transshipment between the locations at the same region,and unidirectional transshipment between the locations at the different region.Each location in the system faced isolated Poisson distribution demand and adopted continuous review(S-1,S)policy.According to the M/G/S/S queue theory,birth and death process model and approximate calculation thought,the inventory models for the loss sales case and backorder case were established respectively.A discrete event simulation procedure for the inventory system was designed to acquire the comparison benchmark.For each variation combination of system parameters,the comparative analysis of computation results for the approximate,simulation,policy simulation,unidirectional transshipment,and no transshipment models,were made.As a result,the fact that the expected total cost of the proposed mixed transshipment approximate model is minimal was found.
