Autonomous distributed scheduling adjustment function with interchanging operations

This paper deals with the partial scheduling adjustment in the autonomous distributed scheduling method. The scheduling adjustment for the production system is required when uncertainty occurs. In that case, it does not need to adjust the whole schedule, but only the partial schedule which receives a direct influence by uncertainty according to the variable situation. From the viewpoint of the distributed system, to implement a function which adjusts such a partial schedule, each machine needs to manage schedule and exchange information. It has been studied by some researchers in recent years. However, the partial scheduling adjustment has not been controlled to change the processing sequence of operations in a machine, namely interchanging operations. Therefore, we propose realizing a function interchanging operations in a machine to diminish the influence occurred by a delay of a certain operation.
