PurposeIn this paper, the authors design accelerated life test and provide its application in the field of accelerated life test. The authors use maximum likelihood estimation method as a parameter estimation method.Design/methodology/approachIn this paper we design accelerated life test and provide its application in the field of accelerated life test. The authors use maximum likelihood estimation method as a parameter estimation method.FindingsIn this study, the authors design accelerated life test under Type-I censoring when the lifetime of test items follows PID and also provides its application in the field of warranty policy. The following conclusion is made on the basis of this study. (1) An inverse relationship is shown between the shape parameter with the expected total cost and expected cycle time, while the shape parameter directly relates to the expected cost rate (see Table 5). (2) A direct relationship is shown between the scale parameter with the expected total cost and expected time cycle, while the inverse relationship is shown with the expected cost rate (see Table 5). (3) An inverse relationship is shown between the replacement age and the expected cost rate, while there are direct relationships between expected total cost and expected time cycle (see Table 5).Originality/valueThis paper is neither published or neither accepted anywhere.

For analysing ALT efficiently and to obtain performance data, the experimenter needs to determine the testing method, statistical model, form of the life data and a suitable statistical method. Analysing these measures properly, provides the best estimates of the product's life and performance under usual conditions.There are researchers who combined accelerating life testing and warranty models. GuangbinYang, (2010), provided a method for describing the warranty cost, and its confidence interval. El-Dessoukey (2015) used accelerated life tests along with Exponentiated Pareto distribution to describe age replacement policy under warranty policy.The article describes how to use accelerated life testing procedures for predicting the cost of age replacement of units or products under warranty policy. Under constant stress, the generalized exponential distribution is assumed to cover the lifetimes of the products. The chapter also describes the age replacement policy in the combination of pro-rata rebate warranty for non-repairable units. Model Description and Test MethodALT is a best used method for reliability and life prediction of systems or components.

In This Paper, we focus on estimating the expected total cost and expected cost rate for age replacement under warranty policy. We describe how to use design of Accelerated life testing (ALT) plans by assuming constant stress and life times are independently distributed as Exponentiated Pareto Distribution (EP) for predicting the cost of age replacement under warranty policy. This problem is studied when maximum likelihood estimators (MLE) are obtained. Also, the Age Replacement Policy under Pro-rate Rebate Warranty is displayed. Finally, numerical examples are carried out to illustrate theoretical results.
