In order to improve rationality of evaluation index weight and realize the reasonable evaluation of pig farm standardization,this paper used the combination method of precise value,interval value and triangular fuzzy number to construct the judgment matrix,and adopts the fuzzy consistency matrix to avoid the consistency test and improve weight precision to improve fuzzy analytic hierarchy process.An evaluation model of pig farm standardization based on improved fuzzy analytic hierarchy process,membership degree and European closeness degree was established,and comprehensive evaluation of three pig farms with different breeding scale was carried out.Pearson correlation between evaluation value and the number of fattening pigs per sow per year （MSY） was analyzed.And the sensitivity of the evaluation model is also analyzed.The results showed that the standardization of each pig farm was at different levels,and the evaluation scores were HI_A=0.639,HI_B=0.675,HI_c=0.744.It was significantly positively correlated with MSY_A=17.5,MSY_B=19.15,MSY_C=22.54.With MSY as the grading standard,pig farms A and B were rated at level 4,while pig farm C was rated at level 2.The evaluation results are consistent with the reality,and the evaluation model is reasonable and effective.Moreover,the changes of investment,site planning,enclosure construction,production management and biosafety factors are highly sensitive to the final evaluation results.
