金刚石钻头综合评价灰色优化理论模型与应用

Gray Optimization Theory Model of Comprehensive Evaluation of Diamond Drill and Its Application

根据灰色关联度的定义，本文运用扩展的最小二乘方准则构造目标函数，建立了金刚石钻头综合评价灰色优化理论模型，并以胶东金矿区金刚石钻头统计资料为例，介绍了其具体应用。

According to the definition of gray relevance degree,by using the rule of expansive minimum two-multiplication,the author constructed the objective function and built the gray optimization theory model of comprehensive evaluation of diamond drill.Also considering the statistical data of diamond in Jiaodong gold mining area as an example,the author introduced its application,the result of which is consistent with other methods.
