ABSTRACT:
An industrial expert system for use in designing a plant system or device thereof and in fault detection, includes a knowledge base having a rules-section for describing deductive inference rules. Also included is an expression-section for describing a calculation formula of equality with either a right side or left side being a simple term having a value and the other side being polynomial including known functions. Also included is an attributes-section for declaring the nature and value of each of the attributes cited in calculation and inference and for declaring parameters for controlling communication between a process of deductive inference and a calculation process according to calculation formulas. A deductive inference engine performs deductive inferencing on the basis of the rules, calculation formulae and the attributes stored in the knowledge base. This system uses a simple construction to efficiently perform detection of fault logic by using specific formula or calculation of parameters representing features of a fault which are to be performed during an inference.
