Abstract

Conceiving applications as sets of autonomous agents is a prominent approach to the construction of complex distributed systems. Particularly attractive are decentralized application designs that enable adaptive, robust and scalable applications by allowing agents to self---organize. Tools to the construction of self---organizing MAS, e.g. decentralized coordination strategies, catch increasing attention in MAS research. However, their purposeful utilization challenges current development practices. The intended non---linear macroscopic dynamics hinder top---down designs on the drawing board and corresponding development procedures rely on sequences of manual system simulation. In order to stimulate methodical development and facilitate the validation of complex MAS by simulation, we present a systemic approach to the qualitative validation of macroscopic MAS dynamics. Describing MAS as dynamical systems enables developers to formulate hypotheses on the intended macroscopic MAS behaviors that guide system simulations. We discuss and exemplify how to (1) derive systemic models as well as hypotheses from MAS designs, (2) infer appropriate simulation settings to their validation and (3) interpret the obtained results. In addition, work in progress on the automation of both system simulations and their interpretation is outlined.
