Keywords:

In this paper, we explain how to analyze and design the accelerated life test plans to improve the quality and reliability of the product. This study’s key feature is to estimate the costs of maintenance service policy because it plays a significant part in assisting any manufacturing organization for sale and available its equipment and maintenance cost-effective. The constant-stress partially accelerated life test is assumed when the lifetime of test units follows two-parameter Reduced Kies (RK) distribution under a multiply censoring scheme. The maximum likelihood estimates, Fisher Information matrix, and the asymptotic variance and covariance matrix are obtained. The confidence intervals of the estimators are also obtained. In addition, a simulation study is conducted to ensure the accuracy of the results.
