双基点法和价值工程法是 2种较好的数值优选法 ,但它们均存在一些缺陷 .作者将双基点法改进后“嫁接”到价值工程法之上 ,提出了一种相似率价值工程法 .该方法不但集中继承了这 2种母体方法的优点 ,而且克服了它们的缺点 ,针对采矿生产实际 ,舍弃了其数学原型中一些不必要的环节 ,简单精确 .实践证明 ,该方法应用到地下采矿方法的优选中具有明显的优势 ,具有一定的应用价值 .
Two-point method and value engineering method are two better methods of numerical optimization, but they all have some shortcomings.The authors propose a similarity-ratio value engineering method by improving the “double-point method” and “grafting” to the value engineering method. The method not only inherits the merits of these two kinds of parent methods but also overcomes their shortcomings. According to the actual mining practice, it discards some unnecessary steps in the mathematical prototype and is simple and accurate.It has been proved that this method is applied to underground mining The optimization of the method has obvious advantages and has certain application value.
