Dynamic production management architecture considering preparative operation

Abstract

Automated factories have become complicated and need higher flexibility to satisfy various requirements today. In this environment, many concepts of autonomous & distributed production systems have been proposed for a dynamic production management recently. In this paper, the preparative operations are discussed, that is focused on the decision of production process order with consideration of set-up time, and a dynamic production management architecture considering such preparative operations is proposed. First, the decision rule of the processing order by using production process information and real-time production system information is introduced. Then, we also pay attention to the combination and timing of processing sequences on both machining cells and parts in order to propose the timing rule and the set-up time rule referring to the real status of that are applied to be dynamic scheduling. Finally, real-time production-scheduling system using the proposed rules is developed, applied to a case study, and it is shown that the proposed system has the feasibility of the flexible correspondence against the disturbance. © 2008 International Federation for Information Processing.
