应用可拓分析研究了数控设备故障停机率降低策略。引入关联函数计算关联度,并采用自顶向下分析法确定权重系数,得出数控设备重要程度等级,以此确定数控设备故障停机率降低策略。通过实例表明,这种分析方法具备可行性。
The application of extension analysis to study the numerical control equipment failure down rate reduction strategy. The correlation function is introduced to calculate the degree of correlation, and the top-down analysis method is used to determine the weight coefficient. The grade of importance of numerical control equipment is obtained, so as to determine the strategy to reduce the failure rate of numerical control equipment. The example shows that this method is feasible.
