The Research On Child Safety Seats Comfort Evaluation By AHP-fuzzy Comprehensive Evaluation

Children's safety seat is closely related to children's daily travel.Parents are increasingly paying attention to the safety and comfort of children.The evaluation of the comfort level of children's safety seats has important practical significance.This study explored the importance of various influencing factors in the evaluation of comfort of children's safety seats from multiple directions and proposed a child safety seat comfort study based on a multilevel fuzzy comprehensive evaluation method.The impact factors affecting the safety seat is extracted by literature research and data analysis.Taking the characteristics of safety seat comfort evaluation as the starting point,a combination of qualitative and quantitative methods is used to determine the comfort evaluation index,and multilevel analysis method and fuzzy synthesis are used.The construction of a comprehensive evaluation system for the safety seat and determination of evaluation index calculation methods using Matlab2014 a software to analyze the weight of each indicator in the evaluation process.Using AHP and the fuzzy comprehensive evaluation method are applied organically to the safety seat comfort evaluation to construct a safety seat comfort evaluation model.The current status of the safety seat comfort survey is used as an example to verify the relevant conclusions.To verify whether the weight distribution of each influencing factor is reasonable.By the comprehensive index system and index weight distribution,a safety seat comfort evaluation program is established.The use of big data analysis methods and big data visualization technology is expected to break through the limitations of traditional safety seat comfort evaluation methods and the safety seat comfort evaluation.The way will be presented in a quick,intuitive and innovative way.The innovation of this paper using a multilevel analysis method to determine the factor weight ratio that affects the comfort of the safety seat and build an evaluation system for the comfort evaluation of the all-round child safety seat,so that the safety evaluation of the safety seat systematizes scientifically.Using fuzzy mathematics model to construct the safety seat comfort evaluation model and combining with the commonly used percentage system scores to calculate the comfortable and specific score of a certain all-round safety seat,so that the user can understand the comfort and cost performance of the safety seat more intuitively and simply.
