Demonstratable lifetime of different RDTs - simulation and calculation

The dataset file contains data of different reliability demonstration tests (RDTs). For this dataset, an RDT is a failure-based test for a product with Weibull distributed failure times (due to a single failure mechanism), which are load-dependent according to the inverse power law, and which are evaluated using maximum likelihood estimation. Each RDT is capable of demonstrating a particular lifetime t_RCS for a given required reliability and confidence, and with probability of test success of 80 %. t_RCS is obtained from both a classical simulative approach, including MLE and Fisher confidence bounds, and from an analytic approximation. The error of the latter, as well as the indices of a reduced dataset are given.

本数据集文件收录了各类可靠性验证试验（Reliability Demonstration Tests, RDTs）的相关数据。针对本数据集，可靠性验证试验指针对单一失效机理下失效时间服从威布尔分布（Weibull distribution）的产品开展的基于失效的试验；该类失效时间符合逆幂律（inverse power law）的载荷相关性，并通过极大似然估计（maximum likelihood estimation）进行评估。每一项可靠性验证试验均可针对指定的可靠性与置信度要求，证明产品的特定寿命t_RCS，且试验成功率为80%。t_RCS可通过两种方式获取：一是包含极大似然估计（MLE）与费希尔置信限（Fisher confidence bounds）的经典仿真方法，二是解析近似方法。同时给出了后者的误差，以及精简数据集的相关指标。
