物流配送路径选择的多目标优化模型及其字典序解法

The Multiobjective Optimization Models and Lexicographic Method of Logistic Distribution Routing Selection

根据物流配送路径选择问题的特点与约束要求,建立其多目标优化模型,进而利用字典序思想,提出了相应的字典序求解方法,即:首先最小化配送成本,然后在配送成本不增加的基础上最小化配送时间。文中实例计算表明,所提出的模型与方法可行、有效,可为物流配送路径选择问题提供决策支持。

Based on the characteristics and constraint requires of the logistics distribution routing selection,the article establishes the multiobjective optimization models and proposes the corresponding solving method of the lexicographic order,which optimizes the distribution costs firstly,and then minimizes the distribution time on the basis of the optimal cost,utilizing the idea of the lexicographic order. The calculations of the actual examples in the article indicate that the models and method proposed above are feasible and effective and can provide decision support for the logistics distribution routing selection.
