模糊层次分析法在调剖措施选区中的应用

目前调剖措施选区中存在影响因素多、盲目性大等缺陷,为此,引入模糊层次分析法。在0.1~0.9标度的基础上量化调剖措施各评价参数,建立模糊一致矩阵,结合最大隶属度原则,优选出不同区块各评价参数的隶属度,最后将这些隶属度值组合得到各评价参数对最终结果的评价结果。该方法结合了定性和定量分析,消除了专家权重分配困难的缺陷,减少了人为因素的影响。基于以上原理,将此方法应用在聚丙烯酰胺反相乳液调剖选区中,结果表明该方法可降低调剖区块选择的盲目性,使决策结果更加科学合理,并能提高调剖措施成功率。

Application of Fuzzy Analytical Hierarchy Process (FAHP) in the block selection of profile control measures

Aimed at the current defects in the block selection of profile control which is influenced by various factors and usually carried out blindly onsite,this paper introduces the Fuzzy Analytical Hierarchy Process (FAHP) into the block selection of profile control.Based on the 0.1-0.9 scales,this paper quantifies the appraisal parameters of the profile control,and establishes the Fuzzy consistent matrix.Combined with the maximum degree of membership,grade of membership of each parameter was optimized in the candidate blocks.Finally,combined with all these degrees of membership together,ultimate appraisal of each parameter was achieved.The quantitative and qualitative analysis was integrated,thus assignment of weighting factor was more objective.This method has been applied in the block selection of Polyacrylamide(PAM) Inversion Emulsion profile control.The result shows that this method is quite effective in reducing blindness of block selection,and the decision making is more reasonable and scientific.
