"Reliability" is one of engineering indicators for describing the performance of an item or 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.

Modern industry have property of contrast and fastness of products development, so that the high costs that occur because of failure machines due to failure, Therefore analysis reliability is an important factor from point of view of the factory managers and the costumer .This research focuses on studying and evaluating the reliability of one of production system factory as a basis to study the reliability of systems and the ways of calculate it, which consist of: A) Failure Data collection .

B) Failure representation, simulation and drawing graphically the histogram and probability plot in order to calculate Time To Repair TTR and Time Between Failure TBF.

C) Calculate the β-value of weibull distribution for the plant.

D) Analyzing the charts to determine the age stage from parts and to calculate the optimistic prediction maintenance time.

E) Analyzing the effect of failure mode in order to calculate the Risk no.

estimation.

Data analysis has been done with support a computer aided program.

Its clear from the analysis of the data of the plant for Kiln and some components of department, are in the third (last stage) of their cycle life, which is the wear-out and aging stage .

This is due to the β-value of weibull distribution.

Which was β= 3.87 so that we focus more on the analysis's of their data as a case-study for the factory.
