HardSys-applying expert system techniques to electromagnetic hardening

Abstract

The application of expert-system techniques to the electromagnetic hardening domain is briefly described with regard to a prototype named HardSys, written in Prolog and containing a subset of the domain knowledge. In this system the domain knowledge is partitioned into four electromagnetic hardening considerations: the ambient field; the shielding effectiveness; the system susceptibility; and the probability of failure. Each of these hardening requirements is implemented as a separate adviser module. Each module can be used independently and each can use information produced by any of the other modules if that information is available and/or required. Such is the case, for example, with the probability of failure module which requires the knowledge deduced from the ambient field, the shielding effectiveness, and the equipment susceptibility advisers. Preliminary results are reported to be encouraging.<>
