This paper deals with object-oriented modeling of an autonomous distributed manufacturing system and its application to real-time production scheduling considering unscheduled disruptions. The autonomous activities of the components of the manufacturing systems are analyzed in order to realize a distributed autonomous real-time scheduling system which can cope with such disruptions as breakdown of equipment and interruption of high priority lots. An object-oriented model is developed to represent the activities of the individual components and communication among the components. Decision-making criteria of the individual components are established in order to carry out real time scheduling. A prototype of a distributed autonomous scheduling system has been implemented in smalltalk, and applied to the real-time production scheduling problem considering unscheduled disruptions. It is shown, through case studies, that the method proposed here is effective for realizing a scheduling system to cope with unscheduled disruptions.
