Manufacturing Information Management and Integrated Capacity Planning in a High Mix Electronics Manufacturing Environment

The high-end electronics manufacturing industry is challenged by the nature of medium/low volume and rich mix as it involves the management of various products and an extensive number of production recipes in a mixed productionflow. In addition, facing dynamic demands and the large amount of system transactions required to successfully manage the entire process further intensifies the complexity of the highmix supply chain. The key to enhance supply-chain operations of this complex process is the efficient use of information systems to (1) ensure the transparency of demand and (2) supply capacity data to all companies within a manufacturing supply chain. This will place companies in a position to anticipate demand fluctuations and respond accordingly. In the previous study [3], authors have introduced the development of the integrated capacity planning model in a high-mix electronics manufacturing environment. This ongoing study further enhances the model with the incorporation of sectionized yield information to improve the planning accuracy and the manufacturing execution information to validate the accuracy. In the previous study [3], an integrated capacity planning tool, composed of Tool Capacity Planning System (TCP) and Integrated Planning System (IPS), was introduced. TCP, an Advanced Planning and Scheduling (APS) tool, consists of a simulation system and a database that can be used to plan for the necessary equipment capacity with demand data. IPS is used for workload and staffing requirement planning. In this research, we further introduce the addition of the Manufacturing Data Warehouse (MDW), which hosts the operational data obtained from the manufacturing execution system. This addition enables the achievement of the abovementioned objectives, incorporation of sectioned yield information to improve the planning accuracy and the manufacturing execution information to validate the accuracy. The organization of this paper is as follow. The need and concept of integrated capacity planning are first described, followed by a review of some related works. The methodology section introduces the concept of unit hour and sectionized yield, as well as planning validation. Followed are several aspects of system development, including design guideline, requirement analysis, system architecture and system modeling. Some illustrated examples of said development activities are presented as well.© 2003 ASME
