Paper Abstract

This paper is a preliminary study on fault monitoring and on-line supervisor reconfiguration to achieve the fault-tolerant operation in cascaded manufacturing processes. To this end, we propose the on-line fault analysis scheme and the corresponding multiagent supervisory control policy by utilizing the index function defined at each state in the discrete event model of the unit processes. Based on the quantitative analysis of the abnormal status into the mutual fault and the essential failure, each agent supervisor of the unit process either makes the on- line fault-tolerant operation or the failure diagnosis in real- time.
