Reasoning about the behaviour of large industrial processes is a difficult and complex computational task. To perform it efficiently requires the use of numerous specialized representations of the system. Any successful information processing system in such an environment must have effective ways to manage these representations, the individual reasoning tasks which use them, and the flow of information between them. This paper addresses these issues by proposing a model centered view of knowledge and presents a domain independent representation language along with operators for managing multiple overlapping models of dynamic physical systems. Examples are given of its use in sensor interpretation, diagnosis and planning in a simple pipe-and-tank network.
