计分法在矿井通风系统方案优选中的应用

Application of Scoring Method to Mine Ventilation System Schemes Optimization

矿井通风系统的最优方案的选择是一个多因素多目标决策问题,目前主要应用的数学方法理论有模糊数学、灰色系统理论和层次分析法等方法,但上述方法均存在计算量较大的问题。计分法是一种在已给定的多个备选方案中,且备选方案各项指标的权重已经确定的基础上进行计分选择的方法,该方法计算简便,概念直观,计算过程可由Excel办公软件完成。结合某矿山矿井通风工程实例,从技术先进性、安全可靠性和经济合理性三个方面12个指标进行了方案选优分析,并与灰色关联分析法进行了比较。计分法也可以应用于其他工程方案的选优。

Many mathematical methods are being applied to the process of selection of mine ventilation schemes at present, such as fuzzy mathematics, grey system theory and analytical hierarchy process. However, the computations of these methods are complicated. The various indicators being pre-determined, scoring method can select optimal ventilation schemes. Its calculation process, accomplished by automation software EXCEL, enjoys features of easy calculation and intuitive concepts. This paper analyzes 12 indicators from the aspects of sophistication, reliability and feasibility using a ventilation project as the subject. Gray Correlation Analysis is applied for comparison. The scoring method can also be used for optimizing other engineering schemes.
