A Review of Simulation-based Intelligent Decision Support System Architecture for the Adaptive Control of Flexible Manufacturing Systems

摘要

The aim of this study is to review the architecture of simulation-based Intelligent Decision Support Systems (IDSS) for real time control of a Flexible Manufacturing System (FMS). The study considers flexibility in operation assignment and scheduling of multi-purpose machining centers, which have different tools with their own efficiency. The study shows that simulation-based IDSS constitutes the framework of adaptive control ler supporting the co-ordination and co-operation relations by coupling a real time simulator, a simulation optimizer and an intelligent DSS for implementing dynamic strategies. The intelligent controllers receive online information of the FMS current state and manage different scenarios of control parameters within real-time simulation data exchange. The simulation-based IDSS uses a posteriori adaptive real time machining process monitoring mechanism that also is online control method acting after the event occurs versus such popular reactive control methods. The study presents the adaptive control ler's bilateral mechanism for simulation optimization based on appropriate control rules that enhance multi performance criteria simulation optimization efficiency. Application of these adaptive control lers showed that they could be an effective approach for real time control of various flexible manufacturing systems. Present method to review is the relevance and chronological appearance of the simulation-based projects for the controlling of the manufacturing systems.
