Study on metamodel-based assessment method for integrated test

In this paper, we consider performance assessment method in integrated test. Test and evaluation (T&E) is defined as the demonstration, measurement and analysis of the performance of a system, and the assessment of the results. The importance of system performance assessment model in T&E is illuminated through mathematical description of integrated test. In order to solve the problems that conventional regression analysis can not deal with nonlinear performance output and complex interactions between different factors in T&E of hightech weaponry, a metamodel-based performance assessment method is put forward. Taking Kriging and radial basis function as examples, contrastive analysis for fitting performances of metamodel and conventional polynomial regression is made. Simulation results show the superiority of metamodel in performance assessment for integrated test.
