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.
