Face the change of globalization business, business opportunities far and wide. In contrast, corporate challengers, is no longer just a regional rival, but the strong competitors from different countries. Now, although the market is large, but also a substantial growth of the overall market supply, the supply quickly exceeded demand. In saturated markets, companies how to overcome or co-competitors to grab a larger market share, profit? For enterprises, existence of the business mission is to provide products, services, customers. Without customers, there is no demand, companies will not be able to survive. Therefore, in addition to providing standard, high quality products, we must be able to respond more quickly to customer needs, get the trust and improve customer satisfaction. Enterprise subject to different tangible and intangible constraints, How to play the best of ability, flexibility and rapid response to customer demand among the existing constraints? Improve operational efficiency, reduce inventory costs, efficient delivery and with the best service in the competition for maximum profit. This study base on many constraints in the continuous industry using thought tool of theory of constraints to break the bottleneck and response customer's demand. Through the ERP combined with ATP / CTP mechanism to improve the order promising process. Effectively improve service efficiency, shorten customer product delivery, while enhancing the overall supply chain efficiency, enhance corporate competitiveness and profitability.

The thesis is mainly a study on the Flexible Print Circuit which was producing manufactured. The research investigates how the FPC operates based on related product capacity data in the conjunction of back end MPS system data of producing scheduling database. Due to system and relative data collocation, it helps a salesman to make a better judgment on the outcome of an order before making promises to customers. In addition, this paper is looking into how applying the related production management method increases the number of the entire production and improves the efficiency on the production line. Then it studies how using this method can temporarily meet the needs of customers¡¦ big orders & cut-in orders before promising customers the date of delivery. Regarding manufacturing procedure of FPC, the purpose for increasing actual output is achieving the maximum production capability and the best arranging procedure. All information was given by different groups of employees from FPC industry, including its Sales Department, Production Management Department, Procurement Department and Supply Department; it also derives from the interviews with station managers and high level managers. With situation simulation and case simulation will be revised on current product line¡¦s output and try to bring up production operation model of FPC Industry. Finally, changing production management and station order to achieve its maximum production on FPC.
