Presented in the paper is MES (manufacturing execution system) architecture, which is suitable for managing FMS (flexible manufacturing system) lines under an ERP (enterprise planning system)environment. An IDEF0-model of an 'order handling' shop floor having an FMS line is developed to identify functional requirements of MES, and then a two-tier MES architecture satisfying the functional requirements is proposed. The proposed MES is composed of a Main-MES (for the main shop floor) and an FMS-ME

This thesis describes a methodology for developing an automated process planning system for machining centers. The proposed approach is compatible with the existing CAD/CAM technologies in that the computer automated process planning (CAPP) system can take certain input workpiece descriptions directly from a computer-aided design (CAD) system, and its output process plans are easily converted to "numerical control commands". The process planning system produces practical process plans taking int

The classical activity cycle diagram (ACD), which is a bipartite directed graph, is easy to learn and use for describing the dynamic behavior of a discrete-event system . However, the complexity of the classical ACD model increases rapidly as the system size increases. This article presents an enriched ACD called the parameterized ACD (P-ACD). In P-ACD, each node is allowed to have parameter variables , and parameter values are passed to the parameter variables through a directed arc . This arti
