在港口空箱需求和供给均为模糊随机条件下,综合考虑港口空箱租赁和空箱调运等因素,建立港口空箱保有量和空箱保有区间的多阶段优化决策模型.通过具体算例验证模型的实用性,并分析了港口空箱租赁受限量、空箱调运成本、空箱需求和供给的不确定性等对港口最优空箱保有量的影响.
Under the fuzzy random empty container demand and supply, considering empty container lease and empty container reposition together, a multiple stage optimization model for a port's empty container inventory and the inventory interval was developed. A numerical example was provided to illustrate the ef- fectiveness of the proposed model, and analyze the effects of the rented empty containers ' quantity, the empty reposition cost, the fluctuation and uncertainty of empty container demand and supply on the port' s optimal empty container inventory.
