By using randam sampling method, which is one of uncertainty quantification method, we can evaluate output's uncertainty from input uncertainty directly. However we can also use this method for complicated systems, usually a large number of samples are required to perform accurate evaluation, and the calculation cost is very high It tends to be.Therefore, in this research, we propose a reverse sampling method as a sampling method to evaluate accurately with a smaller number of samples and investigated it.
