A rule-based system for automated batch HAZOP …
This paper describes CHeCKop, a prototype automated batch HAZop identification system. CHeCKop uses a state-based approach to HAZop analysis. The paper commences by describing a simple batch plant case study. CHeCKop contains a rule-based system which identifies potential hazards or operability issues.

Hazard & Operability Analysis (HAZOP) 1 Overview
HAZOP guide words are key supporting elements in the execution of a HAZOP analysis. According to IEC Standard 61882: The identification of deviations from the design intent is achieved by a questioning process using predetermined "guide words". The role of the guide word is to stimulate imaginative thinking, to focus the study and elicit ...
