英文摘要： For the phenomenon of process parameters coupling and heterogeneous variations stream in the complex manufacturing processes,the research object has been turned from the single working procedure to the whole process,from the product quality characteristic to the process parameters, from the single parameter to the parameter coupling. In addition, the optimal design, error tracing and quality control for the complex manufacturing process have been discussed by the geometry model method, the theory of system control and the math analysis methods. The mainly problems have been considered as follows: 1) the expression of key quality characteristics and mainly variation; 2) the Specific structures of system matrix which express the relations of each working procedures, input matrix which express the influence of variation to quality characteristics and observation matrix which includes sensor deployment information; 3) establishing the evaluate indexs that reflect the performance of process plan and improving process plan; 4) studying the variations coupling mechanism, separating,tracing and forecasting the haterogeneous variations; 5) improving the quality by rough theory. Then, based on theory research, the quality analysis & control softwrae for the whole manufacturing process will be developed to assure the st
