Study on evaluation model and optimal method of man-machine system in car driving

The safety probability of car driving is the evaluation objection. Firstly, the relating factors in driver, car and environment are found out. Secondly, the most important factors in these areas are selected out by using method of duality contrast. Then, the functional relation of evaluation objection and the most important factors is built. In terms of the relations of driver, car and environment, different model of MMS is established. Setting up evaluation goal tree, using the secondary method such as brainstorming, fuzzy statistic would improve efficiency. The model and method can be used to evaluate any kinds of MMS, especially the system in which man is controller. So it is meaningful for the development of China's industry, the evaluation and optimization of complex MMS in industrial design.
