Abstract
A method of facilitating a probabilistic lifting process is provided. The method includes obtaining operational data for at least one turbine engine, defining a plurality of cool-down curves for the at least one turbine engine, identifying a plurality of different start types of the at least one turbine engine, and developing a formula for the at least one turbine engine. The method also includes determining an operating strategy and establishing a design useful life for the at least one turbine engine, developing at least one histogram and a probabilistic model using the operational data, and determining a mission mix for the operating strategy by performing a simulation of the probabilistic model combined with cyclic life expenditure data of the at least one turbine engine.
