改进模糊层次分析法在绿色包装评价中的应用

Application of Improved Fuzzy Analytic Hierarchy Process in Green Packaging Evaluation

目的解决现有的包装产品不符合绿色理念,缺乏统一的规定和评价方法问题。方法建立绿色包装评价体系,在FAHP(模糊层次分析法)的基础上,根据每层指标的特点来确定权重,其中5个一级指标采用层次分析法,13个二级指标考虑到主客观性,采用了专家权重系数和熵权法相结合的方法,最后结合包装产品绿色满意度调查问卷进行包装绿色度模糊综合评价,得出一个包装绿色度评价值。结果以义乌市某包装厂为实例进行验证,发放了500份调查问卷,回收432份。经过运算,得出一个直观的绿色度评价值为80.714,评价等级达到优。结论文中评价指标的建立科学合理,所用方法数据易获取,计算过程简便,结果准确直观,有一定的理论和现实意义。

The work aims to solve the problems that existing packaging products do not comply with the green concept and lack uniform regulations and evaluation methods. A green packaging evaluation system was established. On the basis of FAHP(Fuzzy Analytic Hierarchy Process), the weights were determined according to the characteristics of each layer of indicators. 5 first-level indicators adopted the analytic hierarchy process, and 13 second-level indicators adopted the method of combining the expert weight coefficient with the entropy weight in consideration of subjectivity and objectivity. Finally, combined with green satisfaction questionnaire of packaging product, the fuzzy comprehensive evaluation was carried out to the packaging greenness to obtain an evaluation value of packaging greenness. A packaging factory situated in Yiwu City was used as an example for verification. 500 questionnaires were distributed and 432 were recovered. After calculation, an intuitive green evaluation value of 80.714 was obtained, and the evaluation level was excellent. The establishment of the evaluation indicator in this paper is scientific and reasonable, and the data adopted in the method are easy to obtain, with simple calculation process and accurate and intuitive results, which has certain theoretical and practical significance.
