摘要
以配送中心和中转站的配送能力划分各自的配送范围后,将不确定的边界区域加入道路等级划分为若干配送单元。并选择决策中转站规划配送单元,依据配送单元的配送成本、配送中心及中转站的固定成本和变动成本,建立边界配送区域规划的运筹学模型。应用遗传算法设计了配送单元选择配送中心和中转站的编码方式,编写程序求解模型。
Based on the capacity of distribution center and transfer station, the scope of their distribution region is divided respectively, and the uncertain border region is divided into several distribution units by adding road grade. Firstly, the transfer stations are decided to divide the distribution units. According to distribution costs of the units, the fixed costs and variable costs of distribution centers and transfer stations, the operation research model of border distribution region partition is established. Genetic algorithm is applied to design the encoded scheme, by which distribution units choose the distribution centers and transfer stations, and then the program is written to solve the partition problem.
