| Abstract | ||
| ABSTRACT The study of reliability has appeared in the first decade of the twentieth century. The concentration on this type of study has been crystallized during the (II) World War, via studying the military devices reliability. This type has expanded recently to include the study of commercial products as a result of extraordinary developments on the one hand; and the use of electronic devices and the complex systems on the other. This sort of development has imposed an increasing concern on studying the reasons of breakdowns that may lead to the stoppage of devices and sets in their various kinds. So, the concept of reliability is statistically the probability that the device and/or set may work to fulfill a certain work for a span of time until the breakdown has occurred. The current study aims at estimating the reliability function of Babylon Tires Factory. Two methods have been followed (parametric and non-parametric). The first method is the maximum likelihood method as a parametric one. The second is Kaplan-Meir method as a non-parametric. A distribution has been demonstrated throughout using Komogrov - Simirove test. It is concluded that there was no significant difference between the two methods. . | ||
