中文摘要：
针对传统的灰色多目标决策其各指标的权系数的改变容易导致最优方案发生转移的缺点,对传统的灰色多目标决策作了改进,应用空间点之间的距离远近-距离法则法进行方案优选,扩大了权系数的可变空间,提高了灰色多目标决策的准确度与可靠性。并将距离法则法应用到采矿工程领域进行实例验证,证明改进了的灰色多目标决策方法是一种更好的方法。
英文摘要：
For the change of the weight coefficients of various indexes easily leading to the shift of optimum scheme in traditional grey multi-objective decision-making,this paper presents an improved grey multi-objective decision-making,in which the distances between points in the calculation space is use to select proper scheme,it is called as distance principle method.This method expandes the variable space of weight coefficient and improves the accuracy and reliability of gray multi-objective decision-making.In this paper,the distance principle method is applied to an example in mining engineering,and the result has proved that it is a better method for grey multi-objective decision-making.
