摘要/Abstract

摘要： 单元化生产作为一种较好实现生产柔性与生产效率融合的先进生产方式,在变种变量需求环境下它已被大量生产企业特别是装配式生产企业所采用。生产单元构建问题是单元化生产系统设计的关键问题和首要问题,也是单元化生产研究领域的一个热点。本文研究设备易复制情形下,通过配置多台同质设备来实现生产单元间无物料移动,并保证生产单元间工作量均衡的独立生产单元构建问题。本文在综合考虑换装时间、加工顺序、设备生产能力、产品需求量等多个实际生产要素的基础上,建立了以平均总流程时间和各生产单元总流程时间与平均总流程时间偏差最小为目标的数学模型,并开发了一个启发式算法来求解数学模型,最后通过数值算例验证了模型和算法的有效性。

Abstract: Cellular manufacturing has been adopted by a large number of manufacturers suffering from the manufacturing environment characterized by variable product mix and fluctuant production demand,especially for those who are dedicated to assembly.It has been regarded as a synthesis of production efficiency and flexibility.Cell formation is not only the central and foremost problem of designing a cellular manufacturing system, but also the focus in the research fields of cellular manufacturing. The independent cell formation problem with consideration of easily-duplicated machines is studied to eliminate inter-cell movement by allocating multiple identical machines in cells,and balance inter-cell workload.Considering many real-life factors including setup time,processing sequence,machine capacity,and production demand,a mathematical model is formulated to minimize the average total flow time of all cells and the sum variance between the total flow time of each cell and the average total flow time of all cells.Then a heuristic algorithm is developed to solve it.At last,the effciency of the proposed mathematical model and algorithm is validated through a numerical example.
