Reliable Life
For the Arrhenius-exponential model, the reliable life, or the mission duration for a desired reliability goal, $${{t}_{R}},$$  is given by:


 * $$R({{t}_{R}},V)={{e}^{-\tfrac{C{{e}^{\tfrac{B}{V}}}}}}$$


 * $$\ln [R({{t}_{R}},V)]=-\frac{C{{e}^{\tfrac{B}{V}}}}$$

or:


 * $${{t}_{R}}=-C{{e}^{\tfrac{B}{V}}}\ln [R({{t}_{R}},V)]$$
