Abstract: In this paper, vague lambda-tau methodology has been applied for reliability analysis of object oriented systems (OOS). OOS composed of interacting objects residing in computer memory and containing the data and its associated methods which can be decomposed into a finite number of cooperative objects have been considered for this purpose. In this methodology, the vague set theory has coupled with conventional lambda-tau method to evaluate the vague expression for OR-transition of the Petri nets model. Using this methodology, reliability of OOS can be analysed in a more efficient and effective manner.

Keywords: reliability analysis; vague set theory; object-oriented systems; vague lambda-tau modelling; Petri nets; modelling.
