Abstract :
As the distribution of activity parameters is grey information in stochastic network, the model of GERT network with grey information is put forward. Specifically, the simulation algorithm is analyzed based on the principle of signal flow graph. Additionally, the construction of moment generating function in GERT network with grey variables is studied with elaborate discussion on its main properties. Moreover, a simulation example proves that the influence of grey information on parameters in GERT network can be coped by the model of GERT network of grey information and its algorithm.
