摘要
据实际调查，运用层次分析法，将疫病传入的各外界风险因素指标划分为目标层、准则层和分准则层三个层次。采用EXCEL软件进行数据统计，依次编辑各层次结构模型，构建各层次的判断矩阵和一致性检验。结果表明：猪场的管理措施、生物安全、场址是疫病传入的主要风险因素。据此确立了I级指标和II级指标，从而构建疫病传入的风险因素指标体系。
Abstract
Based on experimentations and applied the analytic hierarchy process the index system of external risk factors on large-scale farm is devided into large level, accuracy level and index level. Data statistics and results are obtained with Excel software, editing hierarchical structure models, the judgement matrix of various hierarch and consistency testing are built up. The result show that farm management practices, Biosecurity and site are major risk factors. Followed by establishment of I level and II level evaluation index weighing, a corresponding model of the whole index system is built.
