| Summary: | 博士 === 國立交通大學 === 工業工程與管理系 === 89 === In order to meet the quick response requirement from customer, the manufacturer imperatively needs a shop floor information system to monitor the production dynamics to improve the productivity and efficiency. The most important task of the system is to provide user to perform customized a shop floor manufacturing flow. It means the product related manufacturing information and decision rules must be flexibly adjusted according to the different customers. Therefore, a shop floor information system needs to possess following criteria: (1) Users are able to set up the required shop floor information and decision rules for a shop floor manufacturing flow before production. (2) The system will collect and analyze the shop floor data according to the preset shop floor manufacturing flow. (3) One can easily adjust the flow in a speedy manner to fit the ever changing product and environment needs. (4) The user can implement and maintain the system with litter (or without any) knowledge of programming skill to reduce the implementation duration and cost.
This study presents: (1) An IDEF1X-constructed shop floor manufacturing flow data model, which has the following features: (a) Early standardization and high reusability of operation template, general process, and enhanced bill of manufacture (EBOMfr). Its contents are pre-sum-up manufacturing information and decision rules for data collection and flow monitoring, including material, equipment, special manufacturing criteria, and rules; and (b) Late customization of work-order process. That is to say, one can set up or adjust the manufacturing information and decision rule based on the special customer requirements at the point of order releasing to reflect the flexibility. (2) A WIP (i.e. work-in-process) execution module integrates this data model to monitor and control the product manufacturing flow on the shop floor. (3) An illustrative example, the WIP Enabler, developed by Mechanical Industrial Research Laboratories of Industrial Technology Research Institute, highlights an enabler framework for WIP system to handle different types of manufacturing among IC packaging companies. (4) A mapping analysis between the WIP enabler and IDEF0 modeling methodology for shop floor manufacturing flow can help users to clearly transform the manufacturing flow of IDEF0 to operation template, general process, EBOMfr and work-order process.
