Reliability Analysis of Computer Hardware System Based on Generalized Stochastic Petri Net

This paper presents a new reliability modeling and analysis method of computer hardware system(CHS) based on generalized stochastic Petri net(GSPN).The formal definition,graphical representation and usage of GSPN are given.The GSPN model of computer hardware system basic unit(CHSBU) which can describe simple structure CHS is established.Aiming at the combination explosion problem in the complicated structure CHS application,the GSPN refined model of CHSBU which can describe complicated structure CHS is established by using model refinement technology.The proposed method are validated by the case study.This work can give theoretical direction for reliability design of CHS.
