摘要:
首先建立了羊只发展的GM（1,1）模型, 结果为:X（k+1）0=135919.6772e0.0283062081+8715.3224e(-2.638216866-26187.4039, 在提出规划设想的基础上, 利用线性规划和常规方法分别对羊只种群结构进行了优化调整, 得出2000年羊只发展数量为200000只, 山绵羊比为3.23∶1。
Abstract:
In this paper, the GM(1,1) model for developing sheep husbandry is built, that is, X（k+1）0=135919.6772e0.0283062081+8715.3224e(-2.638216866-26187.4039. Besides, after a suggestion having been put forward the composition of sheep colony is optimized by using the methods both linear programming and traditional, and the result shows that the sheep quantity will be 200000 in 2000 and the ratio of the goat guantity and the sheep is 3.23:1.
