英文摘要：

Aid decision making tool is the key technology for improving the level of design for testability of equipment. Surrounding the realization of aid decision making system of design for testability, we start research from modeling of design for testability, optimizing algorithm of design and analysis for testability and realizing aid decision making system. On the basis of model that we already had, we give out a new modeling idea which is information model and do research on diagnosis optimizing algorithms during the process of design for testability. Finally, finishing integration of testability model and diagnosis strategy and making research on the key technology of realizing the software platform. This research is the key of realizing aid decision making system of design for testability.
