Risk assessment method and reliability test system based on improved Monte Carlo

The invention provides a risk assessment method based on improved Monte Carlo, which improves Monte Carlo, applies the improved Monte Carlo to risk assessment, decomposes q into r0 and iteratively refined r1,... and rL by using a trivial inequality, and independently calculates the r0 and the r1,... and the rL, so that the calculation speed is improved, the precision of the calculated q is kept, and the risk assessment accuracy is improved. Therefore, the time and precision required by risk assessment are improved. 本发明提供一种基于改进蒙特卡洛的风险评估方法，通过对蒙特卡罗进行改进，并应用到风险评估中，以及将平凡恒不等式将q分解为r0加上迭代细化r1,...,rL，并且分别对其进行独立计算，提高了计算速度的同时保持了计算得到的q的精度，从而提高了风险评估所需的时间以及精度。
