EVALUATION SYSTEM FOR RAILWAY LINE DETERIORATING AND METHOD FOR OPERATING THEREOF

摘要

PURPOSE: A track superannuation evaluation system and an operating method thereof are provided to enable a quantitative superannuation evaluation of a track considering the overall shape of the track instead of an individual superannuation evaluation of each structure of the track, by using an AHP technique for various structures of the track and giving a weighted value to each structure, thereby facilitating a quantitative evaluation of each superannuation evaluation element. CONSTITUTION: A track superannuation evaluation method includes a hierarchical structure establishment step in terms of a track section superannuation evaluation (210); a weighted value computation step by a pair comparison (230); and a track superannuation evaluation step (250). The hierarchical structure establishment step is subdivided into an evaluation criterion and evaluation element selection step (201) and a hierarchy setting step for AHP technique application (203). The weighted value computation step is subdivided into a question making step for a pair comparison by class (205) a question evaluation step by experts (207), a consistency evaluation step for the pair comparison (209), and a weighted value computation step for each evaluation element (211). The track superannuation evaluation step is subdivided into an evaluation element score computation step for each track section (213) and a superannuation score computation step for each track section (215).
