Reliability Analysis using Weibull Distribution ? Kiln of Alsalam Cement Factory as Case Study

Rabie Fatah-Elrahman Atta-Elmanan | Khalid Bushra Elhaj Fadul Mohammed ^[2]

Abstract: In this paper we estimate reliability of a system using Weibull distribution. Reliability is one of engineering indicators for describing the performance of an item or a system by probability functions. Reliability is defined as the probability that an item or system is capable of performing, its intended function in a specified time under given working conditions. The Weibull distribution is a generalization of the exponential distribution. The two-parameter Weibull distribution can accommodate increasing, decreasing, or constant failure rates because of the great flexibility expressed through the model's parameter. This distribution is recognized today as industrial standard. This paper presents the maximum likelihood method for estimating the Weibull distribution parameters. and focuses on studying and evaluating the reliability of equipment as a basis to study the reliability of systems and the ways of calculating it.
