Abstract: The embodiments described herein can provide improved diagnostic repair systems and methods to generate and represent cost optimized work plans. These cost optimized work plans include a plurality of procedures, where each of the plurality of procedures represents at least one of a corrective action or test. The order and arraignment of these cost optimized work plans are arranged to have an optimized average cost of repair, and thus can reduce the costs associated with such repairs. Furthermore, these diagnostic repair systems and methods provide techniques for representing such a cost optimized work plan and guiding a user through such a cost optimized work plan. Specifically, separate graphical user interface elements are generated for each procedure in the cost optimized work plan, with the graphical user interface elements including features designed to guide a user through the procedures in a way that provides an optimized average cost of repair.

Abstract: Methods, systems and apparatus are provided for ranking tests of interest. A set of failure modes of interest and a set of tests of interest are determined. A differentiation factor is then computed for each of the tests of interest, and each of the tests of interest can then be ranked based on their respective differentiation factors.
