模糊综合评判在养殖项目选择中的应用

Application of Fuzzy Comprehensive Evaluation in the Breeding Project Selection

针对河北保定山区某养殖场项目选择问题,根据当地实际情况,从影响养殖业收益的饲料价格、饲养方式、疫病防治、动物的生长发育规律、进出口贸易等5大因素方面分析得到3个前景较好的养殖行业——养猪、养羊、养牛。在此基础上运用模糊综合评判和层次分析理论,结合MATLAB软件,对建立的因素集和评语集进行单因素评判得到模糊评判矩阵,并建立层次结构分析模型研究成对比较矩阵计算权向量,利用模糊合成算子合成求得模糊综合评价矢量,在加权平均原则下计算得出3个养殖项目各自的收益评价值。结果表明,养牛的收益值略高于养猪和养羊,因此该养殖场最适合养牛。模糊综合评判方法的应用,可为农村养殖项目选择提供理论参考。

In order to solve a project selection problem of a farm in Baoding mountainous area of Hebei, according to local actual condition, from farming income feed prices, feeding, epidemic prevention, animal growth and development regularity, import and export trade and so on 5 big factors were analyzed to get 3 breeding industry prospects better, which were pigs, sheep, cattle. Using fuzzy comprehensive evaluation and analytic hierarchy theory, combined with MATLAB software, in establishing single factor evaluation factor set and evaluation set of fuzzy evaluation matrix, and to establish a hierarchy analysis model of paired comparison matrix to calculate weight vector, using fuzzy comprehensive evaluation vector obtained by fuzzy synthesis operator, under the weighted average principle,we calculated these 3 breeding project their own income value. The results showed that the profit from cattle slightly higher than the pigs and sheep, so the most suitable for cattle farm. Application of fuzzy comprehensive evaluation method can provide theoretical reference for rural farming project selection.
