To evaluate and predict component-based software security, a two-dimensional model of software security is proposed by Stochastic Petri Net in this paper. In this approach, the software security is modeled by graphical presentation ability of Petri nets, and the quantitative prediction is provided by the evaluation capability of Stochastic Petri Net and the computing power of Markov chain. Each...

A new class of stochastic Petri nets is proposed in this paper. The Stochastic High Level Petti nets [SHLPNs] are High Level Petti nets augmented with exponentially distributed firing times. The main advantage of modeling homogeneous systems using SHLPNs is that the resulting models are simpler, more intuitive and have a smaller number of states as our examples show.

Structural product form and decomposition results for stochastic Petri nets are surveyed, unified and extended. The contribution is threefold. First, the literature on structural results for product form over the number of tokens at the places is surveyed and rephrased completely in terms of T -invariants. Second, based on the underlying concept of group-local-balance, the product form results ...

This paper describes a new modeling tool for the analysis of non-Markovian stochastic Petri nets (SPN). This tool, called Web-SPN, provides a discrete time approximation of the stochastic behavior of the marking process which results in the possibility to analyze a wider class of PN models with prd, prs and pri concurrently enabled generally distributed transitions. An example is used to show t...
