SYSTEM RELIABILITY ANALYSIS AND MANAGEMENT USING PHYSICS-BASED MODELS EMBEDDED IN A BAYSIAN NETWORK

摘要

A method for assessing reliability in a gas turbine engine system includes using a processor to carry out instructions from a memory to propagate a physics-based model through a Bayesian network to assess reliability for the gas turbine engine system. A system for assessing reliability for a gas turbine engine system includes a memory including instructions to propagate a physics-based model through a Bayesian network to assess reliability for a gas turbine engine system. The system also includes a processor operatively connected to the memory to carry out the instructions. A network interface can be operatively connected to the processor to receive reliability data from operation of gas turbine engines, wherein the memory includes instructions for updating data module or modules based on reliability data.
