Enterprise Transfer Alliance Vehicle Routing Problem Based on Fuzzy Time Windows and its Genetic Algorithm

在对带有模糊时间窗的企业间转运联盟车辆路径问题进行描述的基础上,构建了该问题的多目标规划模型;针对该模型提出了一种混合遗传算法,该算法在经典车辆路径遗传编码的基础上,通过若干转化和修正算法得到了一种三元式编码,并改进了交叉和变异算子;最后通过实例说明了模型和算法的有效性.

After general description of enterprise transfer aliance vehicle routing problem based on fuzzy time windows, a multi-objective mathematical model for the problem is built up. Then, a hybrid genetic algorithm is proposed to this kind of problem. In this algorithm, a ternary type chromosome coding mode is used through some transformation and correction algorithms, based on the classical vehicle routing genetic coding. Additionally, crossover operator and mutation operator aew also improved. In the end of the article, the validity of model and the algorithm is proven by an example.
