Automated HAZOP revisited

Integration of interlock system analysis with automated HAZOP analysis

The paper details the integration of a method for the analysis of interlock systems with a software support system for HAZOP analysis. The proposed software aims to enhance the potential of HAZOP in terms of depth and ef®ciency of the analysis. This enhancement is reached through the continuation of the hazard and operability analysis, limited to a group of events which may hold high risks for ...

ExpHAZOP: Knowledge-based expert system to conduct automated HAZOP analysis

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 ...

PHASUITE: AN AUTOMATED HAZOP ANALYSIS TOOL FOR CHEMICAL PROCESSES Part I: Knowledge Engineering Framework

ion of process: functional representation The device or physical systems can be abstracted into different levels of abstraction. For example, an electronic amplifier is composed of different components including transistors, resistors, capacitors and so on. Each component behaviour can be described in terms of their currents and voltages. Using the techniques described above, a description of d...

Automated conjecturing I: Fajtlowicz's Dalmatian heuristic revisited

We discuss a new implementation of, and new experiments with, Fajtlowicz’s Dalmatian conjecture-making heuristic. Our program makes conjectures about relations of real number invariants of mathematical objects. Conjectures in matrix theory, number theory, and graph theory are reported, together with an experiment in using conjectures to automate game play. The program can be used in a way that,...
