Greatest lower bound of system failure probability in a special time interval under incomplete information about the distribution function of the time to failure of system

The author solves the problem of finding greatest lower bounds for the probability F (v) – F (u),0 < u <, v < ∞, where u=m−σμ33,υ=m+σμ33,andσμ is a fixed dispersion in the set of distribution functions F (x) of non-negative random variables with unimodal differentiable density with mode m and two first fixed moments μ1 and μ2. The case is considered where the mode coincides with the first moment: m = μ1. The greatest lower bound of all possible greatest lower bounds for this problem is obtained and it is nearly one, namely, 0.98430. © 2017, Springer Science+Business Media New York.
