建立了可降解包装材料的绿色度评价指标体系,运用模糊层次分析模型对其进行了评价和分析.通过问卷调查得到定性评价后,利用概率统计的原理对数据进行了处理,构造比较矩阵,并采用和积法计算最大特征根和特征向量,最终得到各指标的相对重要度.然后又计算得到各指标相对于被评价产品的综合重要度.用逻辑推理指派法确定各指标的隶属函数后,得到该指标的隶属度.根据各评价指标的隶属度和综合重要度运用线形加权的方法得到的植物纤维淀粉可降解包装材料的绿色度.最后把6种典型可降解包装材料和传统发泡塑料包装材料的绿色度进行了对比,认为生物质类可降解包装材料具有很好的发展前景.
The indexes system of green degree of biodegradable packaging materials is built and the fuzzy analytical hierarchy process (FAHP) methodology is employed to analyze and assess this system. The qualitative assessment is gained by the survey and the statistics theory is employed to deal with the qualitative data. The pair-comparison matrix is built and the maximum characteristic root and vector are computed by the sum-product method. Then the relative importance degree of every influence factor is computed and the compositive importance degree of every influence factor is gained. The membership function of every influence factor is established by logical reasoning assignment method, then the membership degree is gained. According to the compositive importance degree and the membership degree of every influence factors, the green degree of biodegradable packaging materials is generally assessed. The green degree of six kinds of biodegradable packaging materials is compared with foamed plastics materials; the result is that the biodegradable packaging materials has wide development prospects.
