Abstract (en)

[origin: WO2012163634A1] The invention relates to a method for supporting the controlled fault detection in a technical system, having the steps of acquiring a quantity of observations of the technical system, ascertaining a quantity of possible defective components of the technical system and a quantity of possible tests to be carried out on the technical system on the basis of the quantity of observations, ascertaining a quantity of possible component faults which are consistent with the quantity of observations, ascertaining an absolute reduction of the number of elements of the quantity of possible defective components of the technical system for each possible characteristic value combination of each of the quantity of possible tests to be carried out on the technical system on the basis of the quantity of possible component faults, calculating a first prioritization of the quantity of possible tests to be carried out by determining an absolute reduction to be expected on average of the number of elements of the quantity of possible defective components of the technical system on the basis of the ascertained absolute reduction of each test, ascertaining an absolute reduction of the number of elements of the quantity of possible component faults of the technical system for each possible characteristic value combination of each of the quantity of possible tests to be carried out on the technical system, calculating a second prioritization of the quantity of possible tests to be carried out by determining an absolute reduction to be expected on average of the number of the elements of the quantity of possible component faults of the technical system on the basis of the ascertained absolute reduction of each test, and generating a prioritized list of possible test to be carried out on the basis of the first and second prioritization.
