考虑投资和时间成本的地下物流配送路径优化

Study on Underground Logistics Distribution Path Optimization with Investment and Time Cost Considerations

分析了地下物流系统相对于地上物流系统的特殊性,同时考虑投资成本和时间成本,以总成本最低为目标,设计了地下物流配送路径优化模型,然后选用0-1编码的遗传算法进行求解。通过一则算例,根据模型和算法求得了最优路径,表明了设计模型和算法的有效性。

In this paper, we analyzed the uniqueness of the underground logistics system in relation to the above-ground logistics system, then considering the investment cost and time cost and targeting at the minimal total cost, designed the underground logistics distribution path optimization model and solved it using the 0-1 encoded genetic algorithm. At the end, through a numerical example, we demonstrated the validity of the model and algorithm.
