Abstract: The paper addresses software reliability modeling issues at the early stage of a software development for large-scale software products. The hierarchical view of a software product provides the modeling framework at the system level. This paper shows how to take the hierarchical description and perform the system level software reliability estimation using Petri net mechanisms. The Petri net modeling techniques are proposed for handling the dependency among software modules. Furthermore, this paper addresses issues of early stage software reliability modeling when failure data is not available.
Keywords: Petri nets, software reliability estimation, software reliability modeling.
