Abstract

This paper presents an uncertainty measurement theory approach to evaluate failure possibility from failure factors of buried pipelines. The approach considers five levels of failure possibility and selects twenty failure factors. Single index measurement functions for failure factors are used to calculate the measurement values to the failure levels. The measurement values form a single index measurement evaluation matrix, from which a weight vector is developed using information entropy theory. The multi-index uncertainty measurement is determined from the cross product of the single index measurement matrix and the weight vector. The level of failure possibility is judged by credible degree recognition criteria. The proposed approach is demonstrated to be applicable for evaluating failure possibility of pipelines and outperforms other methods.
