Product reliability

This study presents product reliability on component basis and investigates the possible effects on warranty which constitutes a non-technical issue. Product reliability is a key factor which is used in considering the warranty period. It plays a significant role that a mistake in warranty forecasting costs a lot for companies.The objective is to empirically examine the nature of general reliability of manufactured goods and define a statement about them, based on findings of practicing in an electronics company. In this regard reliability will be stated from the actual manufacturing point of view. A case study was conducted as an application to consider how product reliability results in manufacturing industry. LCD TVs were undertaken to examine. To test reliability, a parametric Weibull model was exploited and hazard rates of products were estimated with linear regression method. For this research, the lifetime data obtained by service departments, censored both left and right, were used in MINITAB14 to produce the reliability results.The results of the analysis build up the basis for evaluating the performance of LCDs in means of service. By the help of it, upcoming failures were forecasted and defined when and how many of them could occur in say six months, a year or two years. The time at which a particular percentage of the production will have failed can be determined
