Evaluation of HardSys/HardDraw, An Expert System for Electromagnetic Interactions Modelling

Abstract

The Department of National Defence and the National Research Council have sponsored the development of HardSys/HardDraw, an expert system for the modelling of electromagnetic interactions in complex systems. This report gives a description of HardSys/HardDraw and reviews the main concepts used in its design. Various aspects of its implementation, user interaction and modelling concepts are evaluated. Some deficiencies are identified and enhancements are proposed to overcome them. Concepts of uncertainty are reviewed and an approach using confidence factors and fuzzy arithmetic is developed. A new method relating both the frequency and time domains is presented and is applied for the calculation of failure index and shielding effectiveness.
