A new F-GERT network model in consideration of the fuzzy information

摘要

Graphical evaluation review technique is a kind of powerful modeling tools whose scope of application covers almost all areas of the national economy. But classical GERT network technology can't solve random network with the fuzzy information parameter. In view of random network with the fuzzy information parameter, a new F-GERT network modeling technique which considers the fuzzy information is proposed in this paper. Moreover, the moments and moment generating function of F-GERT network are constructed and the important mathematical nature of four aspects is discussed in detail. On this basis, the simulation algorithm of F-GERT network is studied using signal flow graph principle. Through simulating the paper concludes that the model of F-GERT network and simulation algorithm which are proposed in this paper can solve the social economy question effectively and the effect is good.
