Research and Application of Expert Safety Testing (EST) Based on Entropy Theory

Abstract

EST use the uniform weights to evaluate the pipeline, making the evaluation results do not truly reflect the risk profile of pipeline, so base on the EST , introduce the entropy theory to improve it. Determine the weight factors of every risk factor by calculating the entropy value of every accident factor, clear out the influence of various factors on the pipeline, make risk scoring methods can be more reasonable, accurately reflect the risk of pipeline case. At last, north line pipeline are evaluated by applying the improving method.
