Solving repetitive production planning problems. An approach based on activity-oriented petri nets

Abstract

In the paper, the problem of flow planning in production systems belonging to a class of Cyclic Concurrent Processes Systems is presented. The possibility of using Activity-oriented Petri Nets approach to model the problem as a discrete event system model, and then to perform simulations with the tool known as GPenSIM is shown. For simulation dispatching rules achieved by the analytical method of production order verification based on constraints sequencing methodology and its computer implementation in the system of production orders verification SWZ is used. This paper shows that the results achieved from GPenSIM agrees with that from SWZ. The proposed approach is easy to implement and can be used as an effective production plans verification tool, to identify problems during the implementation of the control rules on production resources in the form of deadlocks, failure to disclose a bottleneck, or problems with production flow synchronization.
