A Place-Invariant Based Method for Supervisory Control of Workflow Nets
Shingo Yamaguchi,Soichiro Nagano 대한전자공학회 2015 ITC-CSCC :International Technical Conference on Ci Vol.2015 No.6
In this paper, we proposed a supervisory control method for workflow nets. Workflow nets are a particular class of Petri nets, but have analysis techniques for more properties, e.g. logical correctness called soundness, than Petri nets. We tackled the following problem: Given a (plant) workflow net (NP ;M0P ) and a constraint specification, construct a workflow net (NS;M0S) which consists of NP and a (supervisory controller) Petri net NC which satisfies the constraint specification. We proposed (i) a sufficient condition for the existence of (NS;M0S) based on place-invariants, and (ii) a procedure to construct (NS;M0S). The advantage of our method is to enable us to take account of logical correctness which may be lost by supervisory control. We also illustrated the proposed method with an application example and showed its usefulness.
