Bounds on Demonstrated MTBF

Fisher Matrix Bounds

[math]\displaystyle{ \begin{align} & MTB{{F}_{{{D}_{L}}}}= & \frac{1}{{{[{{\lambda }_{D}}(T)]}_{U}}} \\ & MTB{{F}_{{{D}_{U}}}}= & \frac{1}{{{[{{\lambda }_{D}}(T)]}_{L}}} \end{align} }[/math]

where [math]\displaystyle{ {{[{{\lambda }_{D}}(T)]}_{L}} }[/math] and [math]\displaystyle{ {{[{{\lambda }_{D}}(T)]}_{U}} }[/math] can be obtained from Eqn. (DR).

Crow Bounds

[math]\displaystyle{ \begin{align} & MTB{{F}_{{{D}_{L}}}}= & \frac{1}{{{[{{\lambda }_{D}}(T)]}_{U}}} \\ & MTB{{F}_{{{D}_{U}}}}= & \frac{1}{{{[{{\lambda }_{D}}(T)]}_{L}}} \end{align} }[/math]

where [math]\displaystyle{ {{[{{\lambda }_{D}}(T)]}_{L}} }[/math] and [math]\displaystyle{ {{[{{\lambda }_{D}}(T)]}_{U}} }[/math] can be obtained from Eqn. (DCR).
