1. A method for determining a recommended maintenance interval for each of a plurality of units within a fleet of power generation units, comprising:
- collecting operational and unplanned maintenance data for a plurality of units within a fleet of power generation units;
evaluating the operational and unplanned maintenance data;
generating a plurality of failure mode models based on the empirical data;
combining the plurality of failure mode models;
establishing a target operational metric for the combination of the plurality of failure mode models;
generating a fleet recommended maintenance interval for the fleet of power generation units based on the target operational metric;
calculating an operational profile for each of the plurality of units within the fleet of power generation units;
calculating the recommended maintenance interval for each of the plurality of units within the fleet of power generation units based on the operational profile of each unit.

Abstract
A method for determining a recommended maintenance interval for a fleet of units as a function of the operational profile of each unit within the fleet. Models are created at the failure mode level for each component of interest. Models for all of the individual failure modes are combined to result in an operational metric of interest which a business owning the fleet of units may prefer to hold constant for each unit in the fleet. Design evaluation tools may be utilized to evaluate boundaries. A system for determining the recommended maintenance interval.

15. A system for determining a recommended maintenance interval for a unit within a fleet of units, comprising:
-
the fleet of units; at least a first tool configured to measure, collect, and/or capture reliability data of the fleet of units; at least a first storage device configured to record the reliability data of the fleet of units; and at least a first analysis device configured to evaluate the reliability data of the fleet of units; wherein the analysis device is arranged to have an input whereby a user may select an operating metric and the analysis device is configured to generate a recommended service interval based on at least the reliability models and the target operating metric.
