【摘要】 针对一种增一型的分层模糊系统,利用输出变量对输入变量敏感性的分析,确定变量在分层模糊系统中位置排定的方法.针对石油钻井事故预警过程中各个特征变量所起重要性的不同,应用层次分析法来确定其权重系数,避免了人为因素所造成的主观性和不一致性,该方法在实际系统中得到了有效应用.更多还原

【Abstract】 For a kind of hierarchical fuzzy systems,the sensitivity is analyzed between the input variables and the output variables. The position of variables in the hierarchical fuzzy system is given according to the importance of variables. The weight coefficient of variables is confirmed applying the methods of analytic hierarchical process (AHP). Then the methods of structural analysis and the weight coefficient can be applied in the forewarning system of oil drilling.更多还原
