The GGMES takes the 3-tier J2EE architecture for its platform of development and deployment. The usage of workflow technique makes the adjustment of business more flexible. Such a system has the properties of re-usage of resource, extendability and safety.The subsystems of production scheduling, producing quality control and analysis, PlantMetrics, process monitoring and equipment management are stressed. The key developing techniques are also discussed. Now the GGMES has been operating stably in the General Group and acquired good effect.
