1. A method for assisting identification of a defective functional unit in a technical system comprising a plurality of functional units, said method comprising the steps of:

  • subjecting said technical system to a test to obtain a first test result relating to operation of said technical system; and

    using a test model in which information is compiled with respect to which of said functional units were tested in said test, and using a system model in which information is compiled regarding assembly of said functional units in said technical system, automatically processing said test result by analyzing said test result to determine a group of said functional units which could be defective based on said test result, thereby obtaining an analysis result, and using said analysis result to assign respective defect probabilities to the functional units in said group.
