The development of systems capable of handling and diagnosing malfunctions in real time has long been of considerable practical importance. This paper describes the architecture of such a system, called the Procedural Reasoning System (PRS). PRS is based on the notion of a rational agent that can reason and plan under possibly stringent constraints on both time and information. This approach p r o vides the system with the ability to reason in complex ways about dynamic processes, while still maintaining the reactivity required to ensure appropriate responsiveness and control. By considering two large-scale applications in aerospace and telecommunications, it is shown how PRS meets many of the critical requirements for real-time malfunction-handling and diagnostic systems. Finally, PRS is compared with a number of other real-time reasoning and knowledge-based architectures that have been used in similar applications.
