Sensitivity Analysis Method of Uncertainty Based on Conditional Entropy

Abstract:

In order to reduce uncertainty of maintenance support analysis result, the article puts forward a method to analysis the sensitivity of result uncertainty on input parameter. Firstly, the paper analysis the uncertainty measurement methods and uncertainty production mechanism of model output result. Secondly, the sensitivity parameter and sensitivity analysis method which based on conditional entropy thought are given. Thirdly, it briefly introduces blind number theory used in analysis data with uncertainty. Finally, combined with the mean maintenance time model case, the paper illustrates the availability of uncertainty sensitivity analysis method and proves the conclusion that uncertainty sensitivity analysis cant be equated to derivation.
