摘要:

对货运车辆和运输任务进行科学有效调度,有助于提高资源利用率,实现货物运输科学化.对一类带时间窗的车队调度问题进行分析,建立其数学规划模型.由于传统算法求解该类模型较为困难,为此,设计一类启发式算法.该算法利用FCFS规则进行运输任务和车辆的分配,并为车辆设计一组简单的编号来标记车辆所处的位置和到达节点的时间,通过不断更新车辆标号生成一条条车辆任务发送链,最后形成一整套车队调度方案.实例分析验证了该算法的可行性.

Abstract:

It helps improve resource utilization and realize scientific transportation to schedule freight vehicle and transportation tasks effectively. A fleet scheduling problem with time windows is analyzed, and then formulated as a mathematical programming model. A heuristic algorithm is designed because of it is difficult to solve the model using traditional algorithms, where the vehicle is assigned to the transportation tasks using FCFS method. The vehicle label is devised to represent the location and the arrival time of the vehicle. A sub-tour is devised to contain a sequence of chained vehicle-task assignment. Finally, the fleet scheduling solution is proposed. A case validates the feasibility of this algorithm.

Key words: integrated transportation, fleet scheduling, heuristic algorithms, first come first served, time windows
