Performance Analysis of Just-In-Time : A Case Study of Garment Factory

Abstract

The performance of Just-In-Time production system for garment industry was studied. Production rate, percent served demand, and work in process were considered as the performance measurement of production system. The results indicated that Just-In-Time production system can serve demand and reduce work in process. It means that average work in process per day of Just-In-Time production system is lower than average work in process per day of production system in chosen factory at 0.01 significant level. Morever, it was found that increasing Kanban size, work in process and percent served demand are increased. Suitable Kanban size is 66 pieces. The production system can achieve 100 percent served demand and its production rate has no difference from production rate of production system can not significantly serve demand although work in process is reduced. On the other hand, Kanban size is higher than 66 pieces. The production system can achieve 100 percent served demand but work in process is significantly increased.
