Research On Management Technologies Of Mould Design Process

The production of die&mould companies is a typical make-to-order and one-of-a-kind production. The production procedure is dynamic and changeable because the customers'order is unpredictable and the manufacture process depends on the experience. Consequently, the production is hard to be controlled and the delivery time is always delayed. In order to solve the problems mentioned above and enhance the level of management, it is necessary for die&mould companies to apply the Management Information System.According to the design process of mould companies, the characteristics of the design process management are analyzed, the UML method is then used to describe the design process management. Furthermore, the database structure is determined to manage the production data according to the characteristics of the date flow. Dynamic task distribution and message technique are applied to the design process management, concurrent designing and task control is implemented. As a result , the period of the mould design decreases.Based on the methods mentioned above, a master production schedule and design process management system was developed by using MVC architecture and J2EE platform. It has been integrated with eMan (a system for the production management of Die & Mould), and implemented successfully in some mould companies.
