基于时间窗的超市生鲜食品配送模型

Models of Distributing Fresh Food to City Supermarket with Time Windows

针对同城超市配送车辆运行物理路径固定的特征,分析带超市时间窗的生鲜食品冷藏车配送满意度的成本构成及其影响因素,构建包括车辆运行成本、制冷成本和时间窗外的超市机会成本在内的总成本最小的带超市时间窗的生鲜食品冷藏车配送目标函数模型。

There is a fixed path generally on city supermarket distribution.Under these circumstances,based on minimizing the system gross cost,a function model is constructed after analyzing cost elements of distribution what are satisfied to both supply and demand.In the model,the cost includes vehicle cost on delivering fresh food to supermarket in approving time,which cost happens in both operation and refrigeration,and includes Supermarket fine to make up loss for delivering beyond the approved time.
