Designs and analysis of computer experiments have been widely investigated in the past decade. Two approaches seem adopted by engineers, the standard response surface methodology and the Kriging method. This paper describes and compares them briefly in order to present a methodology for computer experiments based on these two classical methods. The objective is to combine the advantages of the two approaches, notably the low cost of the standard experimental designs and the accurate response surface of the Kriging method. The use and the efficiency of this tool is demonstrated empirically through examples.
