基于AHP-FCE方法的滴灌带质量综合评价OA

To address the multi-objective nature,fuzziness,and uncertainty of subjective judgments in the quality evaluation of drip irrigation tapes,this study proposes an integrated AHP-FCE comprehensive evaluation method—combining the Analytic Hierarchy Process(AHP)and Fuzzy Comprehensive Evaluation(FCE)—for the systematic and quantitative assessment of drip irrigation tape quality.Targeting the core quality characteristics of drip irrigation tapes,an analytic hierarchy model was established based on the AHP method,encompassing 3 primary indicators(dimensional specifications,hydraulic performance,and material properties)and 9 secondary indicators.The weights of the indicators were determined via expert scoring combined with a nine-point scale method.Utilizing the FCE method,a five-level evaluation set was constructed,and trapezoidal membership functions were adopted to convert measured data into a membership matrix.The comprehensive score was synthesized through the weighted average method,and quality grades were classified accordingly.Model verification results demonstrated that the judgment matrix of the evaluation indicators exhibited good consistency(CR<0.1),and the weights of the primary indicators followed a gradient distribution of"hydraulic performance(0.637)>material properties(0.258)>dimensional specifications(0.105)",which is consistent with practical application requirements.Sensitivity analysis of the weights indicated that the average rate of change in the scores of the secondary indicators was only 0.21%–2.36%,reflecting strong model robustness.Application of this method to evaluate 10 types of drip irrigation tapes showed that the average comprehensive score of the tested products was 2.645,corresponding to an overall"general"quality grade(only 2 products achieved the"good"grade).Among the primary indicators,dimensional specifications performed the best(average score:4.379),hydraulic performance was the poorest(average score:2.192),and material properties presented a differentiated trend,with some products failing to meet the standards for ash content and tensile deformation.The AHP-FCE method proposed in this study provides a scientific tool for drip irrigation tape quality comparison,precise identification of quality issues,and quality control.It can also be extended to the comprehensive quality evaluation of similar agricultural inputs or other products requiring multi-criteria decision-making.
