Abstract

Cellular Manufacturing is a major component of lean manufacturing which can be achieved by cell formation of machine types. Several methods have been developed for obtaining efficient cell formation by considering ideal conditions. This paper takes into account machine reliability and breakdown conditions to provide a comparatively more realistic solution. A mathematical model is proposed to minimize the total cost of production considering factors such as operating costs, machine relocation cost (dynamic cell formation), inter-cell material handling cost, and breakdown cost. The breakdown cost takes into account machine reliability. The proposed model is tested on standard problems from literature papers using a Genetic algorithm approach. The various costs considered are material handling cost, operation cost, purchase cost, and breakdown cost. Results validate the effectiveness and efficiency of the proposed model. Further, incorporation of worker assignment and sustainability can improve the proposed approach.
