Choose a set of quality attributes with which to assess the architectures (pick success criteria). Choose a set of concrete tasks that test the desired quality attributes. Evaluate the degree to which each architecture provides support for each task. 2 PERFORMANCE ASSESSMENT 35 Performance Metrics Metrics for fault diagnosis and prognosis functional elements form the core performance assessment of a deployed CBM/PHM system. Simulation results and real fault data are employed to project the fielded performance of the system.

Eventually, moving up the hierarchy, the ‘‘system of systems’’ considers the component couplings or interactions. Verification is much less involved than the more complex statistical nature of the validation process, and software quality assurance tools are used to address programming errors and to verify the correctness of the software. A combination of white and black box testing strategies is necessary to carry out the verification as completely as possible. The statistical approach to system validation is depicted schematically in Fig.

13 shows one example of the classification results from application of the diagnostic modules, which is based on the tank 1 level data shown in Fig. 12. 13 show the diagnostic results of the tank 1 leakage fault from three classifiers implemented in the PEDS and the overall results combined using Dempster’s rule of combination. Details of the DempsterShafer evidential theory are discussed in Sec. 4 of Chap. 5. The falsepositive rate (FPR), false-negative rate (FNR), and the fault accuracy rate (FAR) are calculated for each data set.
