Abstract:
This paper describes the design and the implementation of a
new modeling tool for the analysis of non-Markovian
stochastic Petri nets (SPN). This tool, called WebSPN,
provides a discrete time approximation of the stochastic
behaviour 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. WebSPN relaxes some of the restrictions
present in currently available packages thus widening the
field of applicability of PNs. A Web-centered view has been
adopted in its development in order to make it easily
accessible from any node connected with the Internet as long
as it possesses a Java-enabled Web browser. Sophisticated
security mechanisms have also been implemented to regulate
the access to the tool which are based on the use of public
and private electronic keys.
