Abstract:
1. A data processing computer implemented method implemented on a programmed computer comprising: inputting to the computer a plurality of collection data items that are characteristics of a tangible product, said data items having N (N is an integer of 2 or larger) kinds of variates and stored in a collection database; creating a sampling database in a storage medium by randomly sampling from the plurality of collection data items; generating with a CPU an N-dimensional response surface model of a design target for the tangible product, and approximating a correlation of the N kinds of variates as a response surface model with reference to the sampling database; calculating with the CPU a bootstrap optimum solution of the response surface model as a sampling optimum solution; creating a sampling optimum solution database storing a plurality of sampling optimum solutions by repeating the calculating step a predetermined number of times; and obtaining a first estimation index with reference to the sampling optimum solution database, said first estimation index including a variance of the sampling optimum solutions to determine a reliability of the optimum solution, wherein the generating step includes calculating the optimum solution uniquely by using the response surface model.
