Innovation by simulation – using the example of an automated work cell

This article describes the use of the HIDES simulation framework within the context of a planning and control system for an automated work cell. Because of the dynamic complexity of the planning task, this system must be able to monitor itself, and to react as independently as possible to changing external circumstances. In order to achieve this, the planning task is distributed among a number of virtual intelligent agents. Each one of these agents supports a clearly defined task, has its own problem-solving strategies, and can request assistance from other agents. Simulation plays an important part in this system. It is used by the agents to monitor their own solution strategies, and to assess the future consequences of their decisions.
