ATP(Available-To-Promise) 생산전략 및 평준화 생산방식을 적용한 가전제품 생산시스템에 대한 사례연구

Recently, there is a worldwide recession due to severe recession in U.S. and debt crisis in Europe. This situation has promoted the necessity for new business approach to overcome current crisis. In this study, alternative business model was investigated to survive in economic instability for a home appliance manufacturer. First of all, production system of TOYOTA Motor Corp. was surveyed to obtain key ideas. But we realized that it is hard to apply TPS (Toyota Production System) to home appliance production system because the life cycle of home appliances are relatively short compared to automotives. Hence, a new modified production system that takes advantage of TOYOTA production system and Available-to-promise (ATP) system is implemented for a large home appliance company in this case study to show the fundamental tasks required before the ATP implementation, main ATP logic algorithm for normal and abnormal situation, and some insights that can be useful for other companies that are thinking about implementing ATP systems. The outcome of this case study shows a significant performance improvement compared to the previous production system - OTD(On-Time-Delivery) level is increased and the material and goods inventory levels are decreased simultaneously.
