METHOD FOR PRELIMINARY ASSESSMENT OF QUALITY OF DIAGNOSTIC TESTS Russian patent published in 2013 - IPC G06F11/22 G05B23/00 

FIELD: information technology.

SUBSTANCE: disclosed is a method for preliminary assessment of quality of diagnostic tests, consisting in that, based on the description of internal parts of the diagnosed article, an equivalent standard model of connections is formed; for the obtained standard model of the diagnosed article, combinations of input test signals are formed; for each combination of input test signals, parameters of combinations of output signals are determined, wherein at the inputs of the obtained standard model of the diagnosed article, corresponding combinations of input signals are given in a corresponding sequence given in the assessed diagnostic test; for each combination of given input signals, except the first, parameters of combinations of response signals at the outputs of the standard model of the diagnosed article and in characteristic intermediate points between standard models of component parts of the article are determined and, by comparing response signals obtained for the previous combination of given input signals, change in values of response signals is determined; preliminary efficiency of the diagnostic test is calculated; a preliminary decision on sufficient quality of the assessed diagnostic test is made, as a result of which the assessed diagnostic test is sent for refinement or for experimental checking.

EFFECT: shorter time for diagnosing engineering systems.
