Abstract: Based on the scheduling problem of large-scale,long distance and varieties relief materials in inter-regional joint allocation and transportation,a multi-objective optimization model for transshipment scheduling is developed to minimize the total travel time and transportation costs.And a multi-objective co-evolutionary genetic algorithm is also proposed to solve the model.Finally,the validity of the model and algorithm is demonstrated by a numerical example,and the results show that many Pareto optimal solutions can be effectively obtained.

摘要: 针对大规模、远距离和多品种的区际救援物资联动调运问题,以区际救援物资送达受灾城市总时间最短和总成本最小为目标,建立了一个区际救援物资中转调度的多目标优化模型,并设计了一种多目标协进化遗传算法。算例分析验证了该算法能够较好地获取问题的Pareto最优解。
