Ontology-Based Support for Hazard and Operability Studies

An automated system for batch hazard and operability studies

A widely used hazard identification technique within the process industry is HAZOP (hazard and operability study). To overcome the repetitive and time-consuming nature of the technique automated systems are being developed. This work considers batch processes, in which material undergoes processing in distinct stages within the plant equipment items according to a set of operating procedures, r...

Hazard and operability (HAZOP) analysis: A review of basics

Hazard and operability (HAZOP) methodology is a Process Hazard Analysis (PHA) technique used worldwide for studying not only the hazards of a system, but also its operability problems, by exploring the effects of any deviations from design conditions. Our paper is the HAZOP review intended to gather HAZOP-related literature from books, guidelines, standards, major journals, and conference proce...

Identification and assessment of hazard in the Refractory Brick Production Company of Gonabad, Iran, using the hazard and operability technique

  Background: In the refractory brick manufacturing industry, because of the high risks associated with the level of dust in the factory environment and thermal stress, a precise identification of industrial hazards is required as a part of safety analysis. The aim of this study was to introduce a preventive approach to risk identification and assessment in the refractory brick production ...

Ontology-based Process Support

This paper describes a principled approach towards creating an IT-support environment for knowledge workers. Starting in the analysis phase our approach paves the way for putting an intelligent assistant to work within a typical business process environment. Thereby, this support intelligence is centred around the interdependencies between documents providing the background knowledge and busine...
