Workscope mix analysis for maintenance procedures
First Claim
1. A method for analyzing maintenance procedures for an article, comprising the steps of:
- providing the article;
defining a set of workscopes that may be performed upon the article;
gathering maintenance frequency information for each type of subsequent trailing workscope that may be performed after a prior leading workscope, for a sample set of maintenance procedures;
determining a measured sample workscope mix in the form of a set of trailing workscope probabilities as a function of each leading workscope, using the maintenance frequency information from the step of gathering; and
projecting a projected workscope mix for a set of maintenance procedures from the measured sample workscope mix.

Abstract
Maintenance procedures for an article such as a component of a gas turbine engine are analyzed by defining a set of workscopes that may be performed upon the article, gathering maintenance frequency information for each type of subsequent trailing workscope that may be performed after a prior leading workscope, for a sample set of maintenance procedures, and determining a measured sample workscope mix in the form of a set of trailing workscope probabilities as a function of each leading workscope. A projected workscope mix is projected for a set of maintenance procedures from the measured sample workscope mix. From the projected workscope mix, labor, supplies, and monetary estimates for maintenance procedures may be calculated. Alternative maintenance strategies may be readily compared using this approach.
