The Application of Delphi Method In the Basic Event Analysis of Pipeline Fault Tree

Delphi method is an effective method in the basic event analysis of pipeline fault tree. The probabilities of the basic event in pipeline fault tree can be estimated by Delphi method which includes following step: design of data form; select of experts; gather and check of data; statistical and fuzzy analysis of data. From the analysis of probability of basic events, the factors affecting pipeline failure are determined.
