| Research Abstract |
(1) A manufacturing execution prototype has been developed study the system configuration, management strategies and so on for the agile manufacturing system which has the ability to quickly adapt to unpredictable changes. It consists of a manufacturing process system and a transportation system.
(2) A high performance real-time scheduling method was proposed in order that each machine autonomously makes the decision about the job to be processed on it. A three-layered neural network is used for the decision-making based on the information about the status of shop-floor collected through the local area network.
(3) A transportation management system has been developed so that multiple AGVs efficiently perform the transportation requests continually arising in the manufacturing system. The proposed system makes the AGVs possible to select the optimal routing without colliding with each other and to autonomously cope with disruptions such as the failure of the AGV and any obstacles being on their way.
(4) A prototype of the manufacturing execution system has been proposed by integrating the hardware and the software of the manufacturing process system and the transportation system developed in this study. The utilization of this system was shown to evaluate the performance of the agile manufacturing systems.
