ExpHAZOP: Knowledge-based expert system to conduct automated HAZOP analysis
نویسندگان
چکیده
HAZOP (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 is comprised of 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 knowledgebase 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. Keyword: HAZOP, ExpHAZOP, knowledge-based expert system, inference engine, optHAZOP
