PRIORITY EVALUATION OF SEISMIC MITIGATION IN PIPELINE NETWORKS USING MULTICRITERIA ANALYSIS FUZZY AHP

摘要：

In general, the cost of seismic mitigation in a lifeline network is large but the budget is limited. Thus, a priority list of pipeline for mitigation is necessary. This paper develops a fuzzy analytic hierarchy process (FAHP) to support decision making for priority evaluation of the pipelines renewal applicable to metropolitan water distribution networks considering customers importance, pipeline properties, and hazard factors. To deal with the uncertain judgment of decision makers, a fuzzy modification of the AHP method is applied as an evaluation tool, where uncertain and imprecise judgments of decision makers are translated into fuzzy numbers. The proposed FAHP method is applied to a case study of Osaka City water distribution network. It demonstrates that the proposed prioritization method can be utilized as an effective tool for tackling the uncertainty and imprecision associated with priority evaluation of seismic mitigation and renewal programs in a pipeline network which can be applicable to mitigation prioritization modeling in other lifeline networks.
