This research dials with discrete counter-part of continuous gamma distribution. In fact, the statistical and reliability properties of this distribution are discuss and some interesting interrelationships. Furthermore, an estimation of the underlying parameter and reliability for this distribution are utilized using different samples sizes, that’s done through different simulation experiments by use (R3.5.1) program, the simulation outputs proved that the Maximum likelihood method gives small bias estimators. An application done at two Soap production machines belongs to the Vegetable Oil Plant. The results show that the second machine which follows DGD (3) is more reliable from the first one.
