Cellular manufacturing system (CMS) is an important application of group technology (GT) in which families of parts is produced in manufacturing cells or in a group of variousmachines. This paper deals with application of a genetic algorithm approach to cellular manufacturing system; a multiobjectivemodel is presented by considering the operation sequence for each type of the parts. The aim of this study is to minimize the cell load variation and part inter/intra cellmovements by proper assignment of machines into cells. At last, the efficiency of the proposed GA approach is evaluated with numerical examples
