Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 236)

Abstract

In order to evaluate and optimize the performance of service composition, a formal description of Grid workflow activity and a model of grid workflow service based on Generalized Stochastic Colored Petri Net are presented in this paper. The token of color of GSCPN can be used to stimulate the different events of message types of business processes. Moreover, Grid workflow service composition algorithm and reduction algorithm based on GSCPN are proposed. Empirical results show that the reduced model reduces the complexity of the qualitative and quantitative analysis of the generated grid workflow service model. The grid workflow service model based on GSCPN can be used for performance prediction and to guide the optimization.
