【摘要】 品位指标优化的方法是矿床勘探、矿山地质等工作中的重要研究课题.本文侧重介绍了最大净现值法、零净现值法、模糊综合评判法和灰色系统决策法等最近出现的几种新的品位指标优化的方法,并对这几种方法的应用和主要优缺点作了简要评述,笔者认为:(1)模糊综合评判法和灰色系统决策法可以推广:(2)不同优化的方法应配合使用.更多还原

【Abstract】 The methods of grade index optimization have been an important subject for the study of the deposit prospecting and mine geology.Several new methods are introduced in this paper. They are methods of maximum net present value, zero net present value, fuzzy complex evaluation,and grey system resolution.Applications, merits and demerits of these methods are reviewed briefly. Lastly, the writer concludes that methods of fuzzy complex evaluation and grey system resolution may be popularized, and that different optimizing methods should be applied together.更多还原
