Abstract
The concept of autonomous control aims at improving the robustness and performance of logistic systems in a dynamical environment. In this context logistic objects are able to make and execute routing decisions autonomously. On the one hand this enables logistics systems to react promptly on dynamic changes and disturbances. On the other hand autonomous control causes an inherent dynamic systems behavior, which depends mainly on decision logic and initial system states. In order to analyze the interplay between these internal dynamics and the overall systems performance, new approaches for describing and classifying the observed behavior are needed. This paper presents an approach, based on Echo State Networks, for identifying and comparing different dynamics, gained by a simulation model of an autonomous controlled production network. It will be shown, that echo-state networks are able to distinguish different patterns of this exemplary autonomously controlled production network.
