畜禽测定的多目标决策模型 I．后裔测定的Fuzzy多目标规划

本文首次将Fuzzy多目标规划的方法引入到动物育种规划的研究之中。通过隶属函数的建立，利用理想点法、线性加权和法和几何平均法，分别研究了兼顾测定总成本和遗传进展时的后裔测定的最佳决策问题，并给出了求Fuzzy解的数值计算方法。最后，讨论了不同方法在实践中的应用。这些方法可被有效地应用到其它类型的动物育种决策之中去。

THE MULTIOBJECTIVE DECISION MODEL IN ANIMAL TESTING I.FUZZY MULTIOBJECTIVE PROGRAMMING OF PROGENY TESTING

The method of Fuzzy multiobjective programming was introduced to the study ofanimal breeding plan. The Fuzzy membership function was established after analyzinggenetic gain and testing cost functions for animal progeny test. The optimum decisionproblem of progeny testing was studied with the ideal point method, the linear weightedsum method and geometric mean method. Taking into account both total testing costand gengtic gain. The practical application of different methods was discussed. Thesemethods could be efficiently applied to other kinds of animal breeding programs.
