Flexibility and transformability of modern manufacturing are determined by many different factors. One of them is an adaptable and dynamic planning of manufacturing processes. The planning systems have not only to guarantee a stable, reliable and quick planning, but also to react to changes and disturbances flexibly and adeqautely. One promising concept is the multi-agents technology. In this work mechanisms and methods for such an agent-based planning are presented that can be applied to the turbulent manufacturing environment.
