Fuzzy Evaluation Modeling and Simulation Research on the Skin Condition Based on CRITIC

Evaluating the skin condition objectively and effectively is not only conducive to the maintenance and improvement of individual skin and making evaluation of skin care products to use utility, but also could be powerful evidence on human health degree. Because a lot of factors have affected the skin condition, it is biased with evaluation by using only a single index. This paper firstly introduced CRITIC method which is based on the data to determine the weight of each single index to maximize the use of test data and information; then synthesize the skin condition index distribution characteristics and the experience of experts and decide to use the normal distribution of the membership function to characterize different index; finally set the membership vectors corresponding to the maximum value as the evaluation grade of the skin condition by the fuzzy matrix synthesis algorithm. The results of the actual test and analysis in lab indicate the effectiveness of the proposed evaluation method.
