Abstract: In this paper, a method with theory of matter element analysis to treat non-comptible problems is introduced, and a model of quality evaluation a-pplied to production of rocket motor is set up. It is shown with examples that this method is simple to be used, the result is intuitive, accurate and easy to be normalized for evaluation by computers. The method may be directly introduced J to some large complicatied engine engineering systems, such as the evaluation of quality of design and products of space vehicle systems.
