矿山特定经营期内的经济效果偏好排序研究

STUDY ON PREFERENCE SEQUENCING OF ECONOMIC RETURNS IN AN GIVEN PERIOD OF MINE

基于矿山特定经营期内的主要技术经济指标为区间数的特点 ,建立了多属性区间数矿山经济效果评价的偏好排序模型。引入了指标标准化的指数函数 ,利用两区间数的优度函数 ,定义了评价方案对“优度”和“劣度” ,并以此进行偏好排序。实际应用表明 ,该模型简单、实用 。

With respect to the feature that main techno economical index in a given period of mine is interval number, a preference sequencing model of multi property interval numbers for economic returns evaluation is built. The model introduces the exponential function of standardized index, defines the goodness and badness of evaluation plan by the help of goodness function of two interval numbers and carries out preference sequencing. The practice shows that the model is simple, practical and presents all round information for decision making.
