Global Sensitivity Analysis of Infection Spread, Radar Search and Multiple Criteria Decision Models

摘要

In the present paper, the method of structure analysis for multivariate functions was applied to examine the global sensitivity of three complex models: the HIV/AIDS infection spread, radar search, and the multiple criteria decisions. The investigation of global sensitivity exposed the most influential parameters or their groups. This knowledge makes it possible to concentrate efforts to obtain exact values of these main parameters. As a rule, only a small part of model parameters has a significant influence.
