Abstract: The simulation, modeling and analysis of manufacturing systems for performance improvement have become increasingly important during the last few decades. This paper presents a practical solution to a manageable and well distributed work in process (WIP) control system with simulation experiment demonstrated by constructing the virtual production lines, addressing issues such as wafer kitting strategy, critical work in process level setting. The simulation WIP instances are coordinated and synchronized with production line influence factors and activities imported. Through the testing and actual practice, this simulation tool helps semiconductor assembly and test factory production managers effectively manage work-in-process (WIP) levels to compensate the impact of unexpected production variations and achieve better factory performance.

Abstract: In terms of transforming supply chain into integrated value systems, the benefits of Early Supplier Involvement (ESI) in product development have been widely accepted. As far as variety management and online configuration are concerned, the difficulties of ESI in online mass customization manifest themselves through two main aspects: (1) Support the seamless information integration with respect to its high variety and large volume not only among internal functions but also with external suppliers; (2) Support real-time online configuration for product configuration generation and optimization based on customer requirements and supplier capabilities. Accordingly, this work proposes two potential solutions. PFA-based integrated information model is established to synchronize the PFA generic structure and supplier product information.
