考虑同一港口内不同船公司之间的合作行为，在港口空箱需求和供给均为模糊随机条件下，空箱租赁不受限，建立船公司合作条件下以港口集装箱物流总成本最小化为目标的多阶段港口空箱保有量优化模型，最后通过具体算例验证模型的有效性，并对船公司合作与不合作条件下的港口集装箱物流总成本和港口集装箱保有量进行比较分析，分析空箱租赁成本、储存成本、空箱需求波动、需求的模糊程度等参数对船公司的港口集装箱物流总成本和保有量进行分析。

With the consideration of fuzzy random empty container demand and supply as well as the corporation of dif-ferent shipping companies in the same port,and without the limit of empty container lease,a multi-stage port container inventory level optimization model based on the minimization of expected container logistics total cost is developed.A numerical example is given to demonstrated the effectiveness of the proposed model and compare the models with ship-ping companies corporation and without shipping companies corporation.At last,the impacts of empty container lease cost,holding cost,empty container demand variation and demand fuzzy degree on port logistics cost and container in-ventory level are analyzed.
