| 摘 要： | 随着现代工程系统的大型化与复杂化趋势，大型复杂系统可靠性评定是亟待解决的问题。工程中常用的可靠性指标有可靠度和平均寿命，平均寿命指标直观、物理概念清晰，使用更加方便。针对有限样本条件下，大型复杂系统平均寿命评定的蒙特卡罗法，提出利用MATLAB进行抽样模拟，大大提高了计算效率，对工程中大型复杂系统平均寿命评定具有重要应用价值。

| Abstract: | With modem engineering system getting larger and more complex, the reliability evaluation for the system is an urgent task to deal with in engineering field. The common reliability targets are reliability probability and M'TTF (Mean Time To Failures). MTTF features directly and distinctly, so it is more convenient. According to Monte Carlo sampling simulation method of MTTF, MATLAB is to be used in sampling simulation, which greatly increases the computing efficiency. It is very important for engineering applications. |
