Abstract: Upon application of first inputs and for a first proposed maintenance event, a lifing model responsively produces a cost of an unplanned failure for an asset. Upon application of second inputs, a performance analysis model responsively produces a cost of degradation of performance of the asset over time. A projected revenue for the asset is based upon third inputs. A profitability of the asset is determined for the first proposed maintenance event. Subsequently, one or more of the first inputs, the second inputs, or the third inputs are adjusted based upon a second proposed maintenance event, and an adjusted profitability determined for the proposed second maintenance event. The adjusted profitability is displayed at the display. One of the proposed maintenance events is selected.
