Implementation of intelligent EMC analysis and design techniques

Prior research performed by the authors indicates that expert systems (ES) embedded with artificial intelligence (AI) constraints provide an excellent environment for establishing "knowledge-enhanced" problem-solving tools for EMC applications. This paper updates the findings of this original investigation into the feasibility of adapting expert systems for generalized EMC analysis and prediction. Specifically, the development and application of the Intelligent EMC Analysis and Design System (IEMCADS) using a proven expert system technology is presented in the context of the Navy's electromagnetic (EM) engineering (EMENG) Baseline II CAD thrust. EMENG is defined as the practical application of the principles of electromagnetics in ship design. IEMCADS is a computer-aided below decks room arrangement module that will be integrated into the EMENG system. EMENG will deliver enhanced capabilities for preventing electromagnetic interference (EMI) early in the ship design process. Specifically IEMCADS is a tool for simulating Navy vessel below-deck electromagnetic environment effects (E/sup 3/) for the purpose of optimizing layout of bounded below-deck regions that encompass racks/equipments, cables, and local magnetic energy sources.<>
