Abstract

The method and system quantify the impact of various design and operational solutions for equipment modules of a structure and the overall structure based upon economic factors. In particular, the method and system provide cost evaluation of various maintenance approaches for at least one equipment module that is part of an overall structure. In addition, a baseline and alternate equipment module may be specified for each equipment module. The costs associated with each of the maintenance approaches for each baseline and alternate equipment module then may be compared and the costs associated with the overall structure having a chosen maintenance approach for each baseline and alternate equipment module may be evaluated. The sensitivity of the costs associated with the overall structure to changes in one or more of the parameter values also may be calculated.
