Abstract :
This paper presents the development and implementation of Motorola´s Graphical Manufacturing Monitoring System (GraMMS) that provides real-time graphical monitoring of manufacturing data including work-in-process (WIP), equipment, throughput, and dispatch rankings. GraMMS consists of four main applications namely; Dynamic Dispatch, WIP Monitoring System (WMS), Equipment Management System (EMS), and Throughput Monitoring System (TMS). GraMMS provides Motorola semiconductor wafer fabs with instant data-driven decision support and trend analysis as well as a short-interval scheduler via discrete-event simulation. The Dynamic Dispatch system is a combination of simulation and heuristics based on concepts from the theory of constraints. This competitive advantage increases output, decreases cycle time, and improves resource utilization
