Automated manufacturing systems (AMSs) are designed to efficiently transform materials into products. The transformation mainly involves three kinds of flows: material, information, and cost. In this paper, we propose a methodology for designing an AMS by constructing a triple flow model (TFM) for the AMS, which in turn incorporates three models: a function model representing material flows and the manufacturing process; an information model to control the manufacturing process; and a cost model to reflect resource utilization and material consumption. Also, the TFM's performance is evaluated and improved. As a holistic solution for AMS design, the methodology integrates manufacturing process design, process control design, activity-based costing, and performance improvement. A mold filling system is employed to demonstrate how to construct the TFM and how to set a control parameter for improving the performance.

In this paper, we propose a design methodology based on SMT (Supervisor-Monitor-Troubleshooter) framework to build a reliable AMS. In SMT framework, 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: supervisor design, monitor design, troubleshooter design, and implementation. Moreover, an AMS called Mold Filling System is employed to demonstrate the effectiveness of the methodology's design and implementation. The methodology proposed here allows a computer system to supervise, monitor, and troubleshoot a remote physical system with significantly enhanced reliability. (C) 1998 Elsevier Science B.V.
