Abstract:

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.
