2016 Maintenance Innovation Challenge Automatic Test Sequence Generator PROBLEM STATEMENT When diagnosing a Unit Under Test (UUT), there exists a fault ambiguity group where a fault is known to exist, but the root cause cannot be isolated. Automated Test Equipment (ATE) uses Test Program Sets (TPS) to diagnose these UUTs. Naval Aviation spends $40 M yearly in acquiring new TPSs and each TPS may take up to 5 years to develop. BENEFITS Automatic generation of Test Program Sets Eliminates man-hours needed for determining tests by hand, generating tests in a fraction of the current time Generation of arbitrary waveform that is optimized to single out faults and remove ambiguity groups TECHNOLOGY SOLUTION Diagnostic unit that automatically optimizes stimulus signals for a UUT, allowing for higher fault coverage without increasing the number of test points Evaluates a set of possible candidate stimulus signals by classification Conducts selection of best candidates Evolves best candidates by mixing and retaining characteristics of previous candidates Unit automatically generates optimal set of signals to stimulate a UUT and detect and isolate faults, eliminating the need to create test program sets through current methods Problem: Diagnostic Ambiguity in Electronic Equipment Solution: Optimized Stimulus Separates Output Responses
