Analysis on Methods of Pipeline Absolute Risk Assessment

A pipeline absolute risk evaluation method is proposed based on a description of a risk value.Based on available information, analysis is made to the consequence that may be generated from destructive events and probability of failure is distributed over each incident's damage status.And analysis is also made to the relationship between the failure probability and risk value.By a probability theory, the sum of index is calculated and the index is translated into failure probability so that a formula to calculate failure probability is established.
