摘要
为适应多品种、小批量的市场需求,单元制造技术应运而生。针对单元制造实施过程中最关键的单元构建问题,在工件多工艺路线的基础上,以单元间及单元内物流量总和最小为目标,利用数学规划法建立单元构建的数学模型;然后采用遗传算法求解,并根据单元构建问题的特殊性,修改了基本遗传算法的编码方式及遗传操作算子;最后从生产实际出发,结合算例证明了结果的可行性,从而验证了算法的有效性。
This article focuses on cell formation,which is the most essential problem in cell manufacturing.Based on multi-process route of parts,with the purpose of minimizing the amount of the logistic in cells and between them,this article uses mathematical programming methods to build cell formation mathematical model and genetic algorithm to calculate.Then modify the basic genetic algorithm for encoding and genetic operators according to the particularity of cell formation.In the end,proceeding from actual production,the article demonstrates feasibility of the results combined with practical examples,and thus verifies the validity of the algorithm.
