不确定需求条件下的物流配送车辆调度问题的研究

针对物流配送车辆调度的问题研究的多样性，文章研究了不确定需求条件下的物流配送车辆调度问题。通过引入决策者主观偏好概念，建立的模糊车辆路径的模糊期望值模型、模糊相关机会规划模型，并提出了求解模糊机会约束规划模型的一种基于模糊模拟的遗传算法；通过随机试验方法研究了决策者主观偏好值对最终决策目标的影响，并得出决策者主观偏好值的选取对最终决策结果有很大影响的结论。

Study on Logistics and Distribution VRP Under Uncertain Demand

Based on the diversity of VRP studies,in this paper,a series of vehicle routing problems under uncertain demand are analyzed.In this paper,the logistics and distribution vehicle routing problem with uncertain demand information is modelled as expected value model and dependent-chance programming through introducing the concept of decisionmaker's preference.Finally newalgorithm is designed for solving the logistics and distribution vehicle routing problem with uncertain demand information.At the same time,de...
