Abstract

The process industry faces a permanently changing environment, where sudden component failures can significantly influence the system performance if not treated in an appropriate amount of time. Moreover, current market trends have to be met such as short production times, a low price as well as a broad spectrum of product and process varieties. Distributed intelligent control systems based on agent technologies are seen as a promising approach to handle the dynamics in large complex systems. In this chapter, we present a multi-agent system architecture capable to answer to the major requirements in the process domain. The architecture is based on agents with diverse responsibilities as well as tasks and separates the control software of agents controlling hardware components into two levels, the high level control and the low level control. Our system architecture has also the ability to flexibly reschedule allocated jobs in the case of resource breakdowns in order to minimize downtimes. This goes hand in hand with a dynamic path finding algorithm to enhance the flexibility of transport tasks. The system is currently tested and evaluated in the Odo Struger Laboratory at the Automation and Control Institute.
