摘要
本文通过对公牛后裔测定遗传进展函数和测定成本函数的分析,建立了遗传进展和测定成本的模糊隶属函数,并应用模糊多目标最优规划的原理,得到了关于公牛后裔测定的模糊最优决策模型,并通过数值例子说明了模型的实际应用。其结果表明,利用本文提出的方法制订公牛的后裔测定方案,可使遗传进展和测定成本都得到很好的兼顾。最后讨论了模糊数学规划在动物遗传育种中的应用问题。
The fuzzy membership functions of genetic gain andtesting cost were established after analysing genetic gain and testingcost functions for bull progeny testing. The optimum fuzzy decisionmodel was got by using the principle of multiobjective fuzzyprogramming and the practical application of the mode1 was demor-strated. The results showed that the progeny testing plan workedout by the method described in the paper could be able to give goodconsideration to both the genetic gain and testing cost. At last, theapplications of fuzzy programming in animal breeding were discussed.
