RELIABLE AUTOMATED MANUFACTURING SYSTEM-DESIGN BASED ON SMT FRAMEWORK

In this paper, we propose a design methodology based on SMT (Superviso r-Monitor-Troubleshooter) framework to build a reliable AMS. In SMT fr amework, supervisors dictate the control logic of AMS; monitors detect faults if they occur, and troubleshooters conduct fault diagnosis and recovery. The methodology includes four stages for building an AMS: s upervisor design, monitor design, troubleshooter design, and implement ation. Moreover, an AMS called Mold Filling System is employed to demo nstrate the effectiveness of the methodology's design and implementati on. The methodology proposed here allows a computer system to supervis e, monitor, and troubleshoot a remote physical system with significant ly enhanced reliability. (C) 1998 Elsevier Science B.V.
