The objective of this paper is to extend the MPSG model by introducing the temporal properties to check time constraint, and do the performance analysis of the real-time shop floor controller. The MPSG (Messagebased Part State Graph) model has been developed for the execution portion of shop-floor controllers that operate in a distributed and hierarchical control environment. It is based on deterministic finite state automata and represents the execution module of shop-floor controller as a communicating fini…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
