多车场多车型多任务的车辆调度优化是城市配送中的典型问题.针对该问题从空驶成本、运输成本和时间成本三个维度构建了一个VRP的数学模型,并采用自适应多态蚁群算法对模型加以求解.通过实例仿真,将仿真优化结果与未优化的随机结果进行了比较.结果发现优化后的成本比未优化的成本低,并且证明了对多车场多车型多任务的VRP模型进行优化非常必要.
多車場多車型多任務的車輛調度優化是城市配送中的典型問題.針對該問題從空駛成本、運輸成本和時間成本三箇維度構建瞭一箇VRP的數學模型,併採用自適應多態蟻群算法對模型加以求解.通過實例倣真,將倣真優化結果與未優化的隨機結果進行瞭比較.結果髮現優化後的成本比未優化的成本低,併且證明瞭對多車場多車型多任務的VRP模型進行優化非常必要.

The multi-depot and multi-task and multi-type vehicle routing problem is the typical problem in city distribution. For this issue, a VRP model is constructed based on deadheading cost, transport cost and time cost. To solve this mathematical model, a self-Adaptive and Polymorphic Ant Colony Algorithm(APACA)has been introduced. A case study is presented to compare the results based on APACA with that under stochastic condition.
