1. A method comprising:
generating a model of a system by a computing device;
simulating the system using the model in each operating state of a plurality of operating states by the computing device; and
based on the simulations, generating a propagation-based fault detection and discrimination (“PFDD”) strategy for each operating state by the computing device to infer trends of signal changes in different operating states for a simulated fault condition at discrete time periods by deriving a deviation index indicative of a deviation of a variable in the fault condition at a time point and a deviation index vector that consists of deviation indexes of the variable at all time points in the simulated fault condition.
