A Colored Petri Net model for NFP driven web service composition

Appropriate composition from the selected set of Web Services (WS) for a specified query is a challenging task. Functional as well as the non-functional parameters (NFP) of the services are to be considered to generate the most relevant composed service. In this paper, we propose a CPN based model for finding the relevant service sequences for composition considering the above mentioned metrics. The offered solution renders more than one composition plan with a ranking for choosing the suitable one. Moreover, the model is simulated by CPN tool for verification of the desirable properties.
