| 摘 要： | 为解决设施面积不等的连续型设施布局问题,建立了基于弹性区带架构布置形式,以物料搬运成本最小、邻近关系最大、距离要求满足度最大的多目标设施布局模型。模型中考虑了区域内的横向、纵向过道,对设施的长宽比进行了限制,使得结果更符合实际情况。为克服传统多目标单一化方法需要人为设置子目标函数权重、主观性过强的缺陷,采用基于带有精英保留策略的非支配排序遗传算法(NSGA Ⅱ)的多目标优化算法求解模型,设计了相应的编码方式、交叉算子、变异算子、罚函数。最后通过某物流园区的实例分析证明了模型与方法的有效性。

| Abstract: | In order to solve continuous unequal area facility layout problem, a multi-objective facility layout model is proposed in the representation of flexible bay structure. The model aims to minimize material handling cost, to maximize adjacency rating and to maximize distance request. The model also takes vertical and horizontal aisles as well as aspect ratio constraints of facilities into consideration, which makes the layout more realistic. In order to overcome the disadvantage of subjectivity caused by the artificial weights of multiple objectives of conventional simplification method, a multi-objective optimization algorithm based on Non-dominated Sorting Genetic Algorithm Ⅱ(NSGA Ⅱ)is proposed as the solving technique. At the same time, the corresponding encoding rule, cross operator, mutation operator and penalty function are designed. The empirical analysis of a logistics park confirms the effectiveness of the proposed model and methodology as a practicable tool for facility layout designers. |
