多目标决策模糊集理论在矿床经济评价中的应用

APPLICATION OF MULTITARGET DECISION OF FUZZY SET THEORY ON ECONOMICAL EVALUATION OF THE MINERAL DEPOSIT

矿床经济评价多方案决策就是如何利用有效手段从可行方案集中选择出经济合理、技术可行、综合效益较好的方案的过程。优或次这一对立概念之间不存在绝对分明的界限，这就是优化的模糊性。另一方面，优或次是方案集中评价指标之间相对比较的结果，这就是优化的相对性。较详细地介绍了多目标决策模糊集理论的数学定义、推演过程和多目标模糊决策模型，并结合科研实践给出了应用实例。

Multi program decision of deposit economical evaluation is the process of using the effective way to choose the reasonable economic program. The opposite concepts of superior and inferior have no absolute boundary line, which is the indistinction of optimization. On the other hand, superior or inferior is the relative comparison between the indexes of concerntrate evaluation of programs, which is the relativity of optimization. The methematic defination and calculating process of multitarget decision of fuzzy set theory, the model of multitarget decision of fuzzy set are introduced in detail. The application example is also provided combined with the scientific research practice.
