FAILURE PROBABILITY ADJUSTMENT TYPE GIS-AIDED SEWERAGE ASSET MANAGEMENT METHOD

摘要

The present invention relates to a sewerage asset management method, which can adjust failure probability of an asset by applying empirical aging aspect per asset type, and can determine degree of danger on the basis of degree of severity and the failure probability, by classifying each component of a sewerage facility from a sewage conduit to a sewage disposal plant as an individual asset systematically, and setting the degree of severity according to the damage of a random asset within a planning analysis range by establishing spatial position or arrangement information and hydraulic connection information of the asset concretely and precisely on the basis of a geographic information system (GIS). Through the present invention, it is possible to establish and use an organic connection structure of the sewage facility asset systematically, and it is possible to predict the result caused by the damage of the asset accurately and at the same time to calculate predicted damage time or failure probability per asset accurately. And, it is possible to use available resources and finances efficiently and to maintain the service level stably, through rapid and overall analysis as to the total sewerage asset.
