An Evaluation Model for Continuous Operating Time Based on Minimum Order Statistic

For some products, such as radars, communication devices and key production line devices, the ability of continuous operating has an important impact on fulfilling tasks. As an important technical index, continuous operating time reflects the ability of products to operate continuously. But statistical model of continuous operating time has not yet been researched. In this paper, the definition of continuous operating time is given. Considering confidence level, an evaluation model of continuous operating time is proposed based on Minimum Order Statistic. Test plans are designed to verify continuous operating time with different consumer risks. Then a prediction model of continuous operating time is also constructed. A numerical example is introduced to illustrate the rationality and engineering applicability of the methods proposed in this paper.
