Title Analytical simulation and PROFAT II: A new methodology and a computer automated tool for fault tree analysis in chemical process industries
Bibliographic information July 2000, Vol.75, No.1. p.1-27. Illus. 40 ref.
Abstract Fault tree analysis (FTA) is based on constructing a hypothetical tree of base events (initiating events) branching into numerous other sub-events, propagating the fault and eventually leading to the top event (accident). It has been a powerful technique used traditionally in identifying hazards in nuclear installations and power industries. As the systematic articulation of the fault tree is associated with assigning probabilities to each fault, the exercise is also sometimes called probabilistic risk assessment. But powerful as this technique is, it is also very cumbersome and costly, limiting its area of application. This article describes a new algorithm based on analytical simulation, which makes the application of FTA simpler, quicker, and cheaper, thus opening up the possibility of its wider use in risk assessment in chemical process industries. A computer-automated tool based on the methodology has been developed.
