N91–11750 Kansas State Univ., Manhattan. INTEGRATION OF TIME-VARYING DATA INTO KNOWLEDGE-BASED SYSTEMS FOR AVIONICS APPLICATIONS Ph.D. Thesis David Scott Hardin 1989 93 p Avail: Univ. Microfilms Order No. DA9016521 Any knowledge-based system that is to be placed in the cockpit must deal with a wealth of time-varying data, and do so in real time. An avionics knowledge-based system thus requires a conventional signal processing front end to identify relevant signal characteristics, a knowledge representation scheme that lends itself naturally to the representation of uncertain numeric data, and an efficient, interruptible inferencing method. A hardware architecture for knowledge-based avionics systems is proposed which consists of a signal processor and one or more symbol processors. The blackboard paradigm is proposed as the basis for the software architecture. Dempster-Shafer theory is used to express uncertain numerical data. It is shown that the Dempster-Shafer formalism and the four-valued logic of Belnap are complementary, allowing numeric and non-numeric expressions of uncertainty to co-exist. It is also demonstrated that the Kalman filter, a common software component of avionics systems, can be used to provide uncertainty information about numeric data to a Dempster-Shafer evidential reasoning system. An initial software implementation developed in the Ada programming language is discussed. Dissert. Abstr.
