Designing a Flexible Production Flow Using IDEF1x --- an IC Packaging WIP System

The IC packaging industry relies heavily on shop floor information, necessitating the development of a data model to flexibly define shop floor information in the production flow. For this purpose, this work designs a novel data model by using IDEF1x. The proposed data model consists of four modules: operation template setup, general process setup, enhanced bill of manufacture (EBOMfr) setup, and workorder process setup. In addition to allowing the user to flexibly define the required shop floor information and decision rules, the data model provides the flexibility to allow one to adopt changes. Since the data model is static, to handle manufacturing data timely this work also suggests a WIP (work-inprocess) execution module to monitor and control production flow. Finally, an illustrative example, the MIRL WIP System integrated the data model with a WIP execution module (developed by Mechanical Industrial Research Laboratories of Industrial Technology Research Institute), demonstrates the effectiveness of the proposed data model.
