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。 Taking into account the cooperation between different shipping companies in the same port, the empty container leasing is not limited under the condition that the demand and supply of empty containers in the port are both fuzzy and random. Under the cooperation of shipping companies, the total cost of port container logistics is minimized Finally, the validity of the model is verified by a specific example. The total cost of container logistics in port and the number of container in port are compared and analyzed with the cooperation and non-cooperation of shipping companies, Leasing costs, storage costs, empty container demand fluctuations, the fuzzy degree of demand and other parameters of the shipping company's total cost of container logistics and container port to carry out an analysis.
