To provide a system 10 for facilitating a probabilistic life diagnostic process for a turbine engine based on mission configuration.

A server 18 of the system 10 stores in a database operational data on at least one turbine engine, a plurality of cool-down curves 60, 62 for the turbine engine, a plurality of different start types 74, 80 of the turbine engine, at least one operating strategy and a design useful life of the turbine engine, analyzes the stored operational data, constructs at least one histogram and at least one probabilistic model using the operational data, stores the histogram and probabilistic model in the database, determines mission configuration for the operating strategy, performs a simulation of the probabilistic model in combination with cyclic life expenditure data of the turbine engine, and obtains a probability distribution of a total cyclic life expenditure by extending a life expended over the design useful life of the turbine engine.
