可用于确定矿井火灾救灾路线的决策信息,一般具有模糊性和不完整性。为探索救灾路线的优选方法,建立采用区间值Vague集理论对救灾路线进行优选的多属性群决策模型。首先确定与救灾路线优选相关的属性因素,同时给出一种考虑区间长度的记分函数公式,采用模糊层次分析法确定属性因素的权重,并采用群决策方法,通过多位专家对路线记分值的集结运算来提高决策的准确性和安全性,最后利用上述模型对某矿井进行实例分析。结果表明:巷道当量长度、井巷通过时间、巷道通行性和巷道烟流变化速度4个因素可以作为矿井火灾救灾路线优选的决策依据,利用改进后记分函数求得的优选结果与实际情况相吻合。
It can be used to determine the decision-making information of mine fire disaster relief route, which is generally fuzzy and incomplete. In order to explore the optimal method of disaster relief route, a multi-attribute group decision-making model of disaster relief route based on the interval value Vague set theory is established. Firstly, the attribute factors related to disaster route preference are determined. At the same time, a score function formula considering interval length is given. The fuzzy analytic hierarchy process is used to determine the weight of attribute factors. By using the method of group decision, Of the assembly operations to improve the accuracy and safety of decision-making, and finally use the above model to conduct a case analysis of a mine. The results show that the factors such as the equivalent length of roadway, the passage time of the roadway, the trafficability of the roadway and the velocity of the change of smoke flow in the roadway can be used as the decision-making basis for mine fire disaster relief route. The optimized result obtained by the improved score-score function is consistent with the actual situation .
