Abstract

Methods and apparatus for computational aggregation of information from an infrastructure system process by analytical programs tracking condition, maintenance, and scoring for both. An integrated score provides additional insights into actual real-life expectations for continued operation for an infrastructure asset. The system may be accessed over a presentation interface that permits “what if” testing, searching for similarly situated assets, incorporation of actual data of inspections and maintenance efforts, as well as data from similarly situated environments and systems. The information may be processed through numerical methods systems and statistical modules in order to obtain correlations, calculations, and predictions of useful life of assets and systems of assets.
