Plant modelling for system safety analysis

This research work is primarily concerned with modelling of process plants for use with hazard identification and hazard analysis techniques, such as the fault tree and the event tree. A new method of modelling which is fundamentally different from the existing ones has been developed. However, most of the important and widely used techniques have first been reviewed. This has been carried out mainly to give an insight into the structure and characteristics of the techniques. Among them the fault tree technique has been used extensively for hazard and reliability analysis purposes in industry. This important use of the technique has been described separately in more detail. The intention was to describe the logical structure of fault trees and also the importance of modelling on fault tree analysis. A case has been analysed for the latter purpose. [Continues.
