修理级别决策的筛分及应用

Screening the Level of Repair Decision and Application Example

介绍了两种修理级别决策的筛分方法 :粗略报废方程和等费用曲线 ;归纳出了应用这两种方法的不同时机 ;推导出较为实用的粗略报废方程 ;提出了利用等费用曲线作修理级别决策筛分的条件 :应选取敏感性较大的参数为变量参数作等费用曲线图 ,同时给出了如何选取敏感性较大的参数的方法。并给出了应用示例。

Two screening methods of the level of repair decision are introduced in this paper: cursory discard equations and equal cost curves The opportunity of applying these methods is induced The practical cursory discard equation is deduced The requirement of applying equal cost curves to make the level of repair decision is put forward: the sensitive parameters should be selected as variable parameters to draw equal cost curves Moreover,the method of selecting sensitive parameters is offered Finally the application example is given
