1. A method of developing a probabilistic lifting process for use with a turbine engine, said method comprising: receiving operational data associated with at least one turbine engine, wherein the operating data includes at lease one of a plurality of cool-down curves, and a plurality of different start types; determining an operating strategy for each of the at least one turbine engines; determining a design useful life for each of the at least one turbine engines; developing a model of the at least one turbine engine using the operational data; and determining a mission mix for the operating strategy by performing a simulation of the model combined with cyclic life expenditure data of the at least one turbine engine.
