Abstract�� The integrative environmental quality is very important to staff working in the submarine cabin. There are many factors affecting the integrated environmental quality in a submarine cabin, such as temperature, humidity, air trace contaminants, particle pollutants, microorganism and noise. To better evaluate thses factors contributing to the environmental quality, an integrated environmental quality evaluation was studied based on D-S(Dempster-Shafer) theory and analytic hierarchy process. Firstly, the specialists get the evaluation results with the AHP(analytic hierarchy process), but usually different specialists have different weight coefficients for the same environmental fact. Therefore, it is very difficult to deal with this issue. To solve the issue, the D-S was introduced to synthesize the different specialist results. The results could effectively fuse multi-specialists uncertainty evaluation results and improve its dependability.
Keywords�� submarine   enviromental quality evaluation   analytic hierarchy process   D-S evidence theory
