Abstract
Purpose-The purpose of this study is to describe the basic-detail definition and features of this approach, to demonstrate the literature of JIT paradigm and to find the best alternative after investigating the working principles of different systems. The study was held in a factory of this company. Methodology-The means of kanban and classical system were tested statistically in order to determine the kanban stock level and classical system differ from each other. Their variances were found and Z test was applied. The simulation was done with respect to the part x for kanban and classical system. Findings-The comparison of the old system with the new system is presented clearly. For the proof of the comparison results, z test and sum of deviations were used together too. The z test proved that the new systems were better than the old systems and also results were found for the sum of squared deviations from the minimum stock. Conclusion-JIT system is surely practicable in Quality management and mostly in Total Quality Management. Some other quality systems began to apply JIT in their own factories. Within the scope of this study, The JIT system supports a better environment for production. By this technique, the scrap rate, lead-time, and the inventory level decrease where efficiency and utilization of the workers and the machines increases.
