Abstract
Two key decisions in designing cellular manufacturing systems are cell formation and layout design problems In the cell formation problem machine groups and part families are determined while in the facility layout problem the location of each machine in each cell intracell layout and the location of each cell intercell layout are decided Owing to the fact that there are interactions between two problems cell formation and layout design problem must be tackled concurrently to design a productive manufacturing system In this research two problems are investigated concurrently Some important and realistic factors such as intercell layout intracell layout operations sequence part demands batch size number of cells cell size and variable process routings are incorporated in the problem The problem is formulated as a mathematical model Three different methods are described to solve the problem multiobjective scatter search MOSS nondominated genetic algorithm NSGAII and the εconstraint method The methods are employed to solve nine problems generated and adopted from the literature Sensitivity analysis is accomplished on the parameters of the problem to investigate the effects of them on objective function values The results show that the proposed MOSS algorithm performs better than NSGAII and produces better solutions in comparison to multistage approaches
