WebOct 31, 2024 · In this section, we first propose the formal definitions of the multi-properties objective reachability problem (MPOR) and the multi-objective sets reachability problem (MOSR) over FKS based on fuzzy logic, and then prove that an MPOR can be reduced to an MOSR in polynomial time. WebAbstract An algorithm is presented for the general Petri net reachability problem. It is based on a generalization of the basic reachability tree construction which is made symmetric with respect to the initial and final marking.
