| 摘 要： | 在配送系统中,配送中心选址问题与在此基础上的车辆路径问题相互影响.为了反映两者之间的相互关系,建立了配送系统优化的双层规划模型.模型上层为配送中心选址问题,下层为车辆路径优化问题.由上层模型给出初始配送中心选址方案;在此基础上由下层模型进行配送车辆路径优化;然后计算上层模型中的供应商到配送中心的运输费用,从而得到上层模型的目标函数;再对上层模型方案进行调整.设计了基于遗传算法与粒子群算法的求解方法.算例分析表明,与两者分别优化相比,双层规划模型可以降低配送系统的总成本,提高配送系统的整体效率.

| Abstract: | In many distribution systems,the location of the distribution centers and the routing of the vehicles from these centers are interdependent.A bi-level programming model for distribution system was proposed to solve distribution center location and vehicle routing simultaneously so that the interactions between the two decisions are reflected.The upper level is about distribution center location problem;the lower level is about vehicle routing problem.The optimization order is: selecting the initial scheme o... |
