基于延迟理论的Supply Hub出库调度模型

考虑了配送准时性和配送成本之间的悖反关系,将延迟理论引入配送调度,研究了订单随机到达、准时配送的supply hub的出库调度问题.考虑订单到达时间的随机性对配送准时性的影响,设计了一个带延迟因子的滚动调度模型,建立了supply hub准时制配送的出库调度多目标规划模型.根据模型的特点,设计了求解模型的克隆免疫算法.最后,结合数值实验,对延迟调度模型和实际使用的调度模型进行了对比分析.研究结果表明,带延迟因子的调度模型相比常规调度策略.能明显降低随机性订单的配送成本.

Supply hub outbound scheduling model based on delay theory

This study discussed a supply hub outbound scheduling problem with order random arrival and just in time distribution, which took the against relationship between the delivery punctuality and distribution cost into account by the delay delivery theory. On the consideration of the influence of order arrival randomness to delivery punctuality, this study designed a rolling scheduling model with delay factor and constructed a multi-objective programming model. According to the model feature, this study designed a immune clone algorithm to solve it. Finally, this study presented a numerical experiment to compare the optimization results of delay scheduling model with other scheduling models. Consequently, comparing with the conventional scheduling strategy, the scheduling model with delay factor could obviously reduce random order of distribution cost.
