The invention, which relates to a method for improving the validity level of diagnoses of technical arrangements, with an equation system that describes the system being produced by a technical arrangement and being tested for structural solvability and singularities, is based on the object of specifying a method that overcomes the problems in the validity level of the previous diagnosis method and that allows even problems that are not purely structural in system designs to be located automatically, this is achieved in that the investigation for singularities is carried out iteratively, with a threshold value for the numerical matrix entries being approximated to a critical value by changing it and redefining it as a function of the result for each new calculation.
A method for improving the validity level of diagnoses of technical arrangements, the method comprising:
A method for improving the validity level of diagnoses of technical arrangements, with an equation system that describes the system being produced by the technical arrangements and being calculated on a computer using different parameters, with the equation system being tested in the form of a matrix for structural solvability and linear dependency, and, if the matrix is structurally regular and simulation problems nevertheless occur, numerical values are in this case included in the structural solvability tests and, in the process, that part of the equation system is determined that causes singularities, and thus that part of the technical arrangement is determined that is subject to the problem, with the only numerical values that are not set to zero being those that exceed a defined threshold value, wherein the investigation for singularities is carried out iteratively, with the threshold value being approximated to a critical value by changing it and redefining it as a function of the result for each new calculation.
