In facility layout design, the problem of locating facilities with material flow between them was formulated as a quadratic assignment problem (QAP), so that the total cost to move the required material between the facilities is minimized, where the cost is defined by a quadratic function. The most proposed models for solving CMS problems are focused on cell formation and intracellular machine layout problem while cell layout is considered in few papers. This paper presents a new mathematical model to solve a facility linear layout problem in cellular manufacturing systems (CMSs). This model layout depends on the distance of machine locations in cells. A number of instances are optimally solved by the Lingo software to validate and verify the proposed model. Finally, computational results are reported and analyzed.<\div>

The design of cellular manufacturing systems (CMS) involves many structural and operational issues. One of the important design steps is the formation of part families and machine cells. In this paper, the most comprehensive one to date with a more integrated approach to CMS design is proposed, where production planning and system reconfiguration decisions are incorporated. Such a CMS model has not been proposed before and it features the presence of alternate process routings, operation sequence, duplicate machines, machine capacity and lot splitting. The developed model is a mixed integer non–linear program. Within this research, we have developed a model in such a way that the system decides on the best routes instead of the user specifying pre–determined routes. The presence of alternative routings is typical in many discrete, production environments. Routing flexibility increases the number of ways to form manufacturing Cells.<\div>
