Risk Assessment of City Pipe Network Based on Matter-Element and Extension Model

Abstract:

Obtain the weight of risk factors at all levels based on AHP analysis model,optimize the third edition of Pipeline Risk Management Manual to establish a new index system.Bring in the matter-element and extension model,according to the established index system and expert scoring results , calculate the correlation function values of each risk characteristics to each of the risk levels,using the figures to reach the risk level of the city pipeline.Through living example shows that this evaluation method is correct.Compared with the general evaluation method,the matter-element and extension analysis model overall consider the weight of the risk factors,expert score and the grade index system.This evaluation method is more accurate compared with the general evaluation.
