Wang, Xiaoting with Limin Song, "Dominant Structure Analysis: Another Approach", 1992
ua435
In this paper, we put forth another approach to the dominant structure analysis, which we call parameter elasticity method. This method is based on the law of differentiability of solution with respect to parameter. It concerns itself with the dominant structure that contributes most to a particular behavior or behavior change. By applying this law, we develop the new method and new qualitative indexes to determine the dominant structure of a system. This new method has some advantages. One is that it can be applied directly to nonlinear systems without linearization. Another is that it can be accomplished within DYNAMO. In some condition, it may be a good guide to model simplification.
