Estimation the Reliability of the Productivity Machines and it's Availability for the Exponential Distribution A Case Study of AL-Qastal Factory for Producing Juice and Carbonated Soft Drinks in Jordan

Abstract

This study aimed to apply the parametric methods in order to estimate the reliability of productivity machines and it's availability, also to estimate the failure rate function in AL-Qastal factory for producing juice and carbonated soft drinks in Jordan. To achieve the study objectives, the study depend on the machines work times and the repair times of the machines, during the period (1/10/2013 – 31/3/2014). The study findings a number of results, including: 1-     There exist a statistically significant (positive) relationship at the significance level (? = 0.05), between the estimated values of the reliability functions R^(t) for the productivity machines and it's availability A(t). 2-     There exist a statistically significant (negative) relationship at the significance level (? = 0.05), between the estimated values of the reliability functions R^(t) for the productivity machines and the estimated values of the failure rate function h^(t). 3-     There are no statistically significant differences at the significance level        (? = 0.05), between the estimated values of the reliability functions R^(t) for the productivity machines. Upon the foregoing results, the study reached to a number of conclusions and recommendations. Keywords: Exponential Distribution, Reliability, Availability, Failure Rate
