Temporal uncertainty and fuzzy-timing high-level Petri nets
Tadao Murata · Medical Entomology and Zoology · 1996
This paper discusses an approach to deal with temporal uncertainty and introduces fuzzy timing in a high-level Petri net model. The main features of the present model are the four fuzzy set theoretic functions of time called fuzzy timestamp, fuzzy enabling time, fuzzy occurrence time and fuzzy delay, all of which capture temporal uncertainty in a form not violating the axiom of measurement recently proposed by Dr. Petri. Fuzzy-timing nets are suitable for time-critical applications since fuzzy time functions can be computed very fast.
