Study on 7D Planning Model of Synthesized Design Method Based on Systems Engineering

From the view of the point of the systems engineering, the model of 7D planning of product design is presented in this paper based on the previous work. The planning of products design includes design ideas, design environments, design objective, design process, design contents, design methods and the design quality evaluation methods, so named 7D planning model. Besides the understanding of the customer requirements, the seven aspects of 7D planning should be considered completely and planned systematically. The paper makes a detailed expatiation of the 7D planning model of synthesized design method based on systems engineering.
