【摘要】：针对空箱调运过程中的空箱需求量的不确定性,建立含有概率约束规划下的空箱调运模型,将概率约束规划转化为确定性整数规划进行求解。考虑堆场空箱准备量满足随机客户需求的程度所引起的公司信誉成本和调运成本,将两者的加权和作为决策目标函数的多目标调运方案。满足随机客户需求的程度记成服务水平,算例表明:随着服务水平提高,公司的信誉损失下降,调运成本上升,公司决策的总成本下降。当服务水平达到某一临界点,再提高服务水平时,决策的总成本反而上升,说明考虑了多目标的空箱调运优化将为班轮公司调运提供依据。
[Abstract]:In order to solve the uncertainty of empty container demand in the process of empty container dispatching, a model of empty container dispatching with probabilistic constraint programming is established, and the probabilistic constraint programming is transformed into deterministic integer programming to solve the problem. Considering the credit cost and transportation cost of the company caused by the degree of the empty container reserve meeting the demand of random customers, the weighted sum of the two items is taken as the decision objective function of the multi-objective transportation scheme. The degree of satisfying the demand of random customers is recorded as the service level. The example shows that with the improvement of service level, the loss of company's reputation decreases, the cost of transportation increases, and the total cost of company's decision decreases. When the service level reaches a certain critical point and then improves the service level, the total cost of the decision will rise, which indicates that the optimization of empty container transportation considering multi-objective will provide the basis for the shipping company.
