abstract

In engineering design, time-consuming simulations may be needed to find the input-output relationship of a system. High Dimensional Model Representation (HDMR) alleviates the need for intensive simulation by approximating the system’s design space with a surrogate model. Although HDMR can provide an overview, specific regions of interest to the designer may require higher accuracy. This paper presents a tool to visualize and interactively improve HDMR accuracy in specified regions of the design space. Regions of the HDMR are selected by iterative brushing in two-dimensional scatterplot planes. Once a region is chosen, designers may concentrate sampling within its bounds to improve the model locally. Regions can be also improved by modeling the error with a localized radial basis function (RBF) metamodel. The effect of local refinement was further evaluated with localized performance metrics. Testing of the tool shows that it can effectively display and improve HDMR models in regions of interest, if there are variables which have a dominating influence on the output.
