A quick sensitivity analysis tool based on response surface method

A quick SA tool based on RSM was raised herein. The theory of SA based on RSM was analyzed, and then the formulation for SA based on RSM was deduced. Two examples were illustrated to test the performance of SA based on RSM. The results show that the SA based on RSM performs well among the non-extremum spaces, and it can also solve the coupling among problems with multi-inputs and multi-outputs. In a word, SA based on RSM is a good and fast SA tool.
