Analytical simulation and PROFAT II: a new methodology and a computer automated tool for fault tree analysis in chemical process industries
Faisal Khan,Shahid Abbas Abbasi +1 more
TL;DR: A new algorithm based on analytical simulation (named as AS-II) is developed, 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.

Models of accident causation and their application: Review and reappraisal
Mark R. Lehto,Gavriel Salvendy +1 more
TL;DR: In this paper, 54 different accident causation models and 16 methods of application are reviewed and it is found that models of human error and unsafe behavior were applied only in a very rudimentary form, which appears to explain certain deficiencies in traditional hazard analysis.

The propagation of faults in process plants: 1. Modelling of fault propagation
B.E. Kelly,F.P. Lees +1 more
TL;DR: In this article, an interactive, computer-based facility has been developed for the investigation of fault propagation in process plants, including fault tree synthesis and alarm system design, while fault propagation has application not only to design methods such as hazard and operability studies and fault trees but also to computer alarm and trip systems.

Computer-aided Synthesis of Fault-trees
Steven A. Lapp,Gary J. Powers +1 more
TL;DR: An algorithm is presented for the synthesis of fault-trees which is deduced directly from a digraph (directed graph) model of the system being analyzed, and a computer program which uses this algorithm is illustrated for a chemical processing system.

An Algorithm For Fault-Tree Construction
TL;DR: An algorithm for performing certain parts of the fault tree construction process is described and a systematic approach to component model construction is presented.
Journal ArticleDOI
Constructing Fault-Trees by Stepwise Refinement
TL;DR: The construction of fault-trees is considered as a sequence of decisions concerning the decomposition of events into subevents and it is shown that cut-set, path- set, failure rate, and reliability bound information is easily obtainable in parallel with the stepwise analysis of the system.
