Constructing mixed failure model and estimating its fuzzy hazard rate function by different methods using simulation

In this paper we work on estimating parameters of compound three parameters (Burr-XII) which is one of time to failure model distribution with two shapes parameters (α,r) and one scale parameter (λ), the three parameters (α,r,λ) are estimated by methods of moments and method of maximum likelihood and also method of Least square
