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 (Pierce and Yurtsever, 1997) 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
