Knowledge based systems and simulation in production

Knowledge based systems can be helpful to give a wider group of users access to simulation. Classifications are given for systems according to their structure and their task-sharing approach. Among the latter are systems that enable automated model creation, support the interaction of user and expert system and others, that utilize simulation as a means of knowledge acquisition. Two examples are given: Simulation Craft and a system that will support rescheduling in production environments by combining expert systems, simulation and manufacturing systems.
