Hierarchy and Fuzzy Evaluation of Risk of Embedded Gas Pipeline

Since the risk factors influencing the embedded gas pipeline are numerous,fuzzy mathematics is applied in risk evaluation to establish hierarchy fuzzy evaluation method.Basic factors affecting the pipeline risk are determined. Take the fuzziness of factors of different categories and in-between factors of same category into consideration,their own weights are provided.Therefore,the risk of embedded gas pipeline could be evaluated.Accordingly,appropriate effective measures could be taken in time to prevent the potential accident possibly occurred at the risky section of the pipeline.
