  7. Abstract:
  8. Increasing competition in global market and different requirements of customers persuade manufacturers to improve the efficiency of their manufacturing activities. For this end cellular manufacturing systems can be introduced as an innovative and compromising practice for companies. Among the necessary decisions for a successful cellular manufacturing design and implementation, production routing selection (PRS), cell formation (CF), group layout (GL) and group scheduling (GS) are the four most important ones. This research investigates these decisions and proposes a new approach to integrate them. We use important production factors such as production volume, operation sequence, operational and setup time, alternative production routings and different costs of production system as well as constraints such as machine capacity and threshold for intercellular movements. A new mathematical model which integrates these decisions is proposed. A novel aspect of this model is concurrently making the CF, GL and GS decisions as well as considering alternative production routing. It also considers the possibility of processing consecutive and non-consecutive operations of a part on a machine, the most exact calculation of material handling costs, scheduling of part production in a batch manner and considering a threshold for intercellular movements. A simulated annealing algorithm is designed and implemented in C/C++ programming language to solve the problem. It is then tested using several problems with different sizes and settings to verify the computational efficiency of the developed algorithm in comparison with the Lingo software. The results indicate the proposed algorithm is able to find optimal or near-optimal solutions efficiently
