Abstract

Cell-formation problem (CFP) addresses the issue of creation of part families based on similarity in processing requirements and the grouping of machines into groups based on their ability to process those specific part families. The CFP is combinatorial in nature and due to difficulty faced in solving related mathematical programming problems; efforts have been made to use evolutionary approaches. Literature highlights that there are many advantages of converting batch type manufacturing system (BTMS) to cellular manufacturing system (CMS). In this paper, mathematical model has been proposed for groups to be emerged naturally. As mathematical model of CFP becomes NP- complete in nature, researchers advocate the use of meta-heuristics. Over the years, many different metaheuristic methods have been used to solve the CFP in group technology application. In the present paper, evolutionary population based method known as Particle Swarm Optimization (PSO) hybridized with assignment algorithm is used to solve cell formation problems. Due to these proposed changes, efficiencies of cell formed significantly increase in comparison to the results available in the literature. Proposed hybrid algorithm is applied to solve 30 different types of randomly generated and 10 standard CFPs, a large verity in terms of number of parts and number of machines required by these parts. For this algorithm, optimal values of parameters were also found with the use of Taguchi method. It is found that the proposed changes in algorithm and parameters obtained significantly impact the results in terms of efficiency values.
群技术应用背景下自然分组的粒子群优化
细胞形成问题(CFP)解决了基于加工要求相似性的零件族创建问题,以及基于加工这些特定零件族的能力将机器分组的问题。CFP在本质上是组合的,因为它在求解相关的数学规划问题时面临困难;人们已经努力使用进化的方法。文献强调了批量制造系统(BTMS)向元胞制造系统(CMS)转换有许多优点。本文提出了群体自然产生的数学模型。随着CFP数学模型在本质上趋于NP完备,研究者们提倡使用元启发式方法。多年来,许多不同的元启发式方法被用于解决群体技术应用中的CFP问题。本文将基于进化种群的粒子群优化算法(PSO)与分配算法相结合,用于解决细胞形成问题。由于这些建议的变化,细胞形成的效率显着增加与文献中可用的结果相比。所提出的混合算法求解了30种不同类型的随机生成cfp和10种标准cfp,在零件数量和这些零件所需的机器数量方面具有较大的真实性。该算法还利用田口法找到了参数的最优值。研究发现,所提出的算法和参数的变化对结果的效率值有显著影响。
