Closed Loop Fuzzy Petri Nets System
Chengjia Li · Journal of Hangzhou Dianzi University · 2009
A novel type of fuzzy Petri nets,i.e.,closed loop fuzzy Petri nets system is proposed in this paper.It forms a closed-loop dynamic system,thus the applications of the present fuzzy Petri nets are expanded.It can be better applied to the system which is interrelated and mutually influenced each other such as the economic systems.A sensitivity vector also is introduced in this paper to characterize the degree of response of every place to the external stimulation.The definition of fuzzy Petri net and its operating rules are given in the paper at first.And then the algebraic matrix computation method is presented to describe formally the dynamic operating process of the fuzzy Petri net.And meanwhile the whole process of state values can be obtained.Finally an example is given to illustrate the above algorithm.
