Abstract

This paper presents a new approach for the evaluation of a system's global state properties. The approach is intented for the application to reactive multiagent system (RMAS) and adresses the evaluation of emergent properties such as global stabilisation. This approach is inspired by statistical physics and thermodynamics, as a way to link the microscopic and a macroscopic points of view. It gives an important role to partition function Z as defined in statistical physics. From this mathematical function can be extracted indicators that represent the global evaluation of the system state based on local phenomena. In this paper, the approach is put into practice by considering a classical reactive multiagent system: bird flocks simulation. The methodology was applied to analyze system stability. Experimental results obtained with a multiagent simulation platform are presented.
