配送中心一体化决策优化模型与算法

Integrated Optimum Decision-Making Model of Distribution Centre and Arithmetic Analysis

为实现配送中心运作决策一体化,构建多物品两级库存和运输决策优化模型.根据分解-迭代和两阶段逐步优化两种不同的分析思路,分别对原模型进行转化,使转化后的各子模型能用目前较成熟的算法来求解.最后提出两种分析思路下的主算法设计方法,将求解各子模型的成熟算法纳入到各自的主算法框架中,从而形成求解原问题的两个不同的完整算法.

An optimization model was proposed to integrate operation decisions of distribution center by taking into account both the transportation and inventory cost of distribution centre and customers. According to the analysis of this methods-decoupling-iteration and two-echelon optimization respectively, the origin model can be transformed into the corresponding sub-models, which can be solved by some available algorithms. Two different main algorithms are then given to make these available algorithms work together.
