The color comfort degree is the fundamental principle of the color design in industrial environment. Based on the fuzzy synthetic evaluation model in fuzzy mathematics, the new model uses analytic hierarchy process to constitute a factor set which will affect the assessing of the colour comfort degree, and analyses the existing research data and applies the grey system theory when the data of some factors are insufficient, to quantify the weight and set up the change curve of the factors. By fuzzy evaluating the comfort degree of each factor with the data on the curve, the new model reduces the subjective judgments in the evaluation model and updates to a more objective and accurate evaluation system-the double-layer fuzzy synthetic evaluation model.

Synthetic Evaluation

Fuzzy synthetic evaluation method is used to evaluate the drivers hazard perception., evaluation system is set up taking drivers psychological for hazard perception, the identification of hazard factor, hazard attitude as the criterion level. The indexs weight coefficient is determined by the analytic hierarchy process, and the fuzzy synthetic evaluation model is established. Through the model testing, if the driver's hazard perception ability evaluation result is good, according to the principle of maximum membership, it is shown that the driving experience, which is beneficial to the forming of the mature hazard perception psychology, the drivers hazard factors identification index deduced from the virtual scene experiment influenced the hazard perception ability deeply. Seen from the distribution of driver hazard perception level, the professional drivers and amateur drivers has the very big difference, so professional training and work experience are benefit for the driver's hazard perception ability.

Abstract Bioretention is an effective best management practice for urban stormwater. This study aims to provide guidance for selecting the best bioretention medium in terms of pollutant removal capacity. Fuzzy set theory was applied with the improved analytic hierarchy process (IAHP) for weight determination, thus forming the fuzzy synthetic evaluation model, to assess the comprehensive efficiencies of certain sand media. This work is the first to use this method to study bioretention. Results demonstrated that the fuzzy synthetic evaluation model was a rational choice for the selection of bioretention media. The studied media were ranked by pollutant removal capacity as follows: Media III > Media V > Media I > Media VI > Media II > Media VII > Media IV. Media I had the best comprehensive removal efficiency and infiltration rate in bioretention. Moreover, the removal rates for Cd2+, Zn2+ and Pb2+ were excellent (>80%), those for Cu2+ and NH+4-N fluctuated from 58.1% to 92.7% and 64.7% to 95.9%, respectively, and those for NO−3-N and TP of the seven media did not show distinct differences.
