Abstract: In product research and development, the decision maker may wish to select the most reliable product from among several competing products. This selection problem is very difficult for highly reliable products, since it may take a long time to observe failures under normal operating condition. To shorten the life-testing time, an accelerated life test is usually used. For life-stree relations following a Weibull-Arrhenius model, this paper proposes a n MLR (Modified Likelihood Ratio) rule to select the most reliable product. A suitable sampling plan which is needed by this rule is also derived. An illustrative example is given to demonstrate the proposed rule.
Key words and phrases: Accelerated life test, Weibull-Arrhenius model, MLR selection rule, sampling plan.
