基于模糊层次分析法的猪舍健康状态量化评价方法与应用

Application and Quantitative Evaluation Method of Piggery Health Status Based on Fuzzy Hierarchy Analytic Process

根据影响猪舍健康状态的因素多、模糊性等特点,建立了从实用性、经济性、场址选址、猪舍管理和创新性等5个方面评价猪舍健康状态多级综合评价指标体系,提出了一种定性与定量相结合的猪舍健康状态多级综合评价方法,通过对指标隶属度综合、权重确定、模糊综合评判和特征值计算等步骤客观地得到评价结果,它能够有效地评价猪舍健康状态并根据评价结果追踪影响猪舍健康状态的因素,实践表明该方法简便、合理、实用。

Due to the many factors and fuzziness of piggery health status, the multi--hierarchical comprehensive evaluation index system from 5 aspects as practicability, economy, location selection, piggery management and innovation was established, which combined the qualitative and quantitative evaluation. Through the steps of index subordinate synthesizer, weight determination, fuzziness comprehensive evaluation and Eigen value calculation, the evaluation result was objectively acquired, which can efficiently evaluate the piggery health status and trace the factors influencing the piggery health status based on the evaluation result. The practices show that this method is easy, reasonable and practical.
