This project focuses on applying expert system technology to software systems for mission planning and flight control. The objective of this three-phase project is to deliver a software system which can be made available to a number of NASA applications. We expect to achieve this goal through a combination of two state-of-the-art approaches: an object-oriented database management system, and an expert system inference engine. Both components will be implemented in the c programming language, with specific emphasis on portability and performance. Phase I will study the feasibility of integrating two specific systems: the vbase object-oriented database, and the clips c language production system. Phase II will produce a working prototype of the combined system. Phase iii will develop the final product. Vbase is a commercial product produced by ontologic specifically to address the complex modeling and high performance needs of the cad/cam/cae market. Vbase combines portability (unix and vms operating systems), high performance, and object-oriented flexibility. Clips is an expert system tool developed at NASA/jsc's artificial intelligence section specifically designed to provide high portability, low cost, and easy integration with external systems.
