Rough control for FMS based on first-order hybrid Petri nets
Lingzhong Zhao · Kongzhi yu juece · 2009
A rough control for flexible manufacturing system(FMS) based on first-order hybrid Petri nets(FOHPNs) is presented.To construct a correctly behavior evolution graph for FOHPNs,a new approach to determine the event of changing a Macro state is developed.Furthermore,an optimization and control algorithm for FMS is presented,and a rough control method for FMS is developed based on rough set theory and the proposed algorithm.Finally,an example shows the effectiveness of the proposed method.
