ExpHAZOP+: Knowledge-based expert system to conduct automated HAZOP analysis
journal contribution
posted on 2023-05-18, 03:13 authored by Rahman, S, Faisal KhanFaisal Khan, Veitch, B, Amyotte, PHAZOP (Hazard and Operability) is a preliminary and systematic approach for identifying hazards and suggesting hazard mitigation measures in a process facility. A knowledge-based expert system, ExpHAZOP+, has been developed to automate the manual HAZOP analysis and accelerate the process. ExpHAZOP+ comprises a graphical user interface (GUI), a knowledge-base and an inference engine. One of the unique features of ExpHAZOP+ is the fault propagation algorithm, an aspect of the inference engine, which defines the propagation of deviations to all downstream equipment. The dynamic knowledge-base of ExpHAZOP+ allows a user to update knowledge while performing the HAZOP analysis and to use that knowledge in the result. ExpHAZOP+ is easy to use and provides results in a standard report format. Crown Copyright © 2009.
