Most of machine industry in Taiwan use ¡§Build to order¡¨ which start the production process until receiving orders. The key of ¡§Build to order¡¨ can be successful or not is quickly response to demand changes. If the production system can¡¦t keep up with changes in customer demand, it won¡¦t be able to process successive demands. Then the backlog will be more and more. So in ¡§Build to order¡¨, whether production system can adjust for changes in customer demand quickly or not is an important issue of ¡§Build to order¡¨.
Kanban System is a mode of production which Toyota JIT system develops. It uses kanbans to control capacity of each workstation strictly. In order to achieve pull system, it uses kanbans to authorize production. Traditional push system must change production plans frequently, and maintain a certain stock between production processes. Pull system uses demands of back-end process to pull the production of front-end process. To achieve the so-called ¡§Just-in-Time¡¨ concept, the system must output the right number of products at the right time.
This study uses system dynamics. According to relevant literatures and models, this study constructs Kanban system with industrial properties. According to demand changes and number of kanbans, this study simulates and analyzes the effectiveness after implementing the Kanban system. Then this study makes some management recommendations.
Conclusions and findings:(1)Under the situation of normal demand changes, Kanban system can achieve quickly response and stability of production systems.(2) Under the situation of excessive changes in demand, implementing Kanban system will increase the backlog.(3)The number of kanbans represents production needs which are additional planned. The system should minimize the number of kanbans to avoid wastes.
