THE OPTIMIZATION OF NUMBER OF KANBANS IN GKCS WITH SIMULATION TECHNIQUE

This paper presents to determine the optimum number of kanbans in Generalized Kanban Control System (GKCS) at three different demand frequencies and keeping the mean processing time as constant. The configuration of the single line with three manufacturing stages is assumed to have flow line production. The manufacturing system is modeled as network diagram of GKCS using discrete event simulation software i.e. Promodel. Simulations studies were performed for the three-stage GKCS model to find the optimum number of kanbans when the machines are subject to with and without breakdown. The optimum number of kanbans is selected in such a way that, where the throughput is maximum, the work in process is low and the machine utilization is high. The customer demand is assumed as 10,15 and 20minutes. Finally the obtained results are justified with GKCS properties
