Fuzzy Comprehensive Evaluation Model of Trapezoidal Fuzzy AHP Empowerment Used in the Evaluation of Barrier-Free Packing For Children's Food

摘要

Children as a kind of weak consumers, the status of their food security are the focus of society and media. In order to study the condition of the barrier-free packing of children's food, combining with children's psychological and physiological characteristics and on the basis of relevant laws and regulations of food and food packing safety, this study uses the screening index of Principal Component Analysis (PCA) to build a set of accessible pre-warning index system for barrier-free packing of children's food and then uses the trapezoidal fuzzy Analytic Hierarchy Process (AHP) to weigh the two-leveled index in the system and establishes the pre-warning model for children's food packing by means of the fuzzy comprehensive evaluation, finally analyzes the relative importance of each index for influencing children's food barrier-free packing based on certain cases and provides some corresponding suggestions to improve the level of barrier-free packaging for children's food.
