Abstract

The theory of reliability is one of the important theories that is attracting great interest in many researchers at present because of its importance in various fields of life especially in determining the age of a particular device and its efficiency and the addition of applications in the field of radar and atmospheric and astronomical observation. The growing interest in reliability studies is due to the rapid technical and technological development and the use of complex systems in various fields. This paper reviews the article of reliability in terms of the reliability function for complete data  of one of the failure time distributions (weibull distribution) and its parameters in different methods using simulation.
