Abstract: We focus on the control of the performance characteristics of workflows modeled with stochastic Petri nets (SPN’s). This goal is achieved by introducing a new model for Artificial Social Systems (ASS’s) behaviours. We also propose new equivalent transfer functions for SPN’s. ASS’s exist in practically every multi-agent system, and play a major role in the performance and effectiveness of the agents. This is the reason why we introduce a more suggestive model for ASS’s. In order to model these systems, a class of Petri nets is adopted and briefly introduced in the paper. This class allows representing the flow of physical resources and control information data of the ASS’s components. In the analysis of SPN we use simulations in respect to timing parameters in a generalized semi-Markov process (GSMP’s). By using existing results on perturbation analysis (e.g., delays in supply with raw materials, failure of equipments, etc.) and by extending them to new physical interpretations, we analyse unbiased sensitivity estimators correlated with practical solutions in order to attenuate the perturbations. A few examples will emphasize these new approaches.
