Abstract
One of the most statistical techniques that used to study and analyze the failure time of a system or a machine is reliability analysis, in this paper we studded and analyzed a series of failures times that occurs respectively in electrical oven performance of (Alfa steel) manufactory for steel industry that is located in Sulaimani city (Iraq), the data under study were (105) observations that has been recorded during three months. using weibull++ software we got that the minimum failure time is (0.01) minute and the maximum reaches to (24) minutes it makes the reliability of the electrical oven decrease to (0.58) which is approximately fifty percentage of performance; It implies that the electrical oven is losing its efficiency.
