An efficient backward execution algorithm in the AND/OR Process Model for parallel evaluation of logic programs is proposed. The efficiency of the algorithm is achieved by means of information acquired during execution of clauses. The algorithm is considered to be efficient in the sense that it issues fewer number of cancel messages and avoids unnecessary resetting operations. Furthermore, it performs independent redoing and resetting more concurrently than other related works.

This paper describes a modularized AI system being built to help improve electromagnetic compatibility (EMC) among shipboard topside equipment and their associated systems. CLEER is intended to act as an easy to use integrator of existing expert knowledge and pre-existing data bases and large scale analytical models. Due to these interfaces; to the need for portability of the software; and to artificial intelligence related design requirements (such as the need for spatial reasoning, expert data base management, model base management, track-based reasoning, and analogical (similar ship) reasoning) it was realized that traditional expert system shells would be inappropriate, although relatively off-the-shelf AI technology could be incorporated. In the same vein, the rapid prototyping approach to expert system design and knowledge engineering was not pursued in favor of a rigorous systems engineering methodology. The critical design decisions affecting CLEER's development are summarized in this paper along with lessons learned to date all in terms of “how,” “why,” and “when” specific features are being developed.
