摘要: 在基于时间竞争环境下设计配送系统时,除了考虑系统的总费用最小外,还应考虑 系统的总配送响应时间最短。根据建模的假设条件,建立了基于时间竞争的配送系统多目标 非线性规划模型,按照模型决策空间所具有的特殊结构,设计了一种求解模型的启发式算法 。用实际调研的数据作为算例对模型进行了数值演算,结果表明,模型实用,算法有效。

Abstract: The design of distribution system was aimed to minimize the total responding time other than the delivery cost in the time-based-competition environment. Therefore, the multi-objective non-linear programming model for time-based-competition distribution system was constructed with certain assumptions as premises. Then, a heuristic algorithm for the model was designed according to the specific structure of the models decision-making space. Finally, the numerical calculation was performed in the model to solve an arithmetic problem in practical investigation. It showed that the decision model was practical and the algorithm was valid.

Key words: time-based competition, distribution system, multi-objective decision model, mathematic programming, heuristic algorithm
