Many stochastic models have been used in solving reliability problems, motivated by a high degree of variability or randomness of the studied phenomena. Therefore different types of stochastic laws derived from the basic distributions are proposed for modelling a hazard-rate function too. The main contribution of the present paper is to proposed new adaptive hazard rate functions, derived from classical models. A numerical example is provided for the introduced models and comparison is also
