Integration of Genetic Algorithm (GA) and Computer Simulation for Optimization of Operator Allocation in CMS

This paper presents an integrated Genetic Algorithm and computer simulation for optimization of operator allocation in Cellular Manufacturing Systems (CMS). This is a challenging issue in Flexible Manufacturing Systems (FMS) and in CMS in particular. A computer simulation model which considers various operators layout is developed. GA is utilized for optimizations of results of various operators layout and AHP utilized to define the weight of variables of fitness function. Previous studies only utilize multivariate analysis methods, Fuzzy C-Means and simulation, whereas this study uses an integrated GA, AHP and simulation. Also, previous CMS studies consider only one type of product whereas this study considers multi product CMS modeling through simulation. Moreover, more robust CMS assessment indicators are used in the proposed model. A practical case study illustrates the effectiveness and superiority of the proposed methodology.
