Description Efforts such as the Army's Rotorcraft Pilot's Associate (RPA) Advanced Technology Transition Demonstration (ATTD) Program have requirements for real-time execution of knowledge-based systems. However, existing computer hardware platforms and software systems (languages, tools, shells, etc.) are not adequate for applications requiring real-time knowledge-based processing. This is not surprising since knowledge-based systems have historically been developed with non-real-time applications as their primary focus (e.g., expert medical consultants, off-line diagnostics, advisors, etc.). Further, these applications generally were not concerned with run-time efficiency, optimal use of computer resources, embedded system requirements (size, weight and power) and other considerations important in addressing real-time processing. The fundamental design concepts necessary for real-time performance were not considered in the design of the languages, shells and tools used for knowledge-based processing. This paper describes research in the development of a real-time knowledge-based system execution environment suitable for use in next-generation Army helicopters. The paper first describes the unique problems which must be solved in real-time knowledge processing applications. We then describe an
