Abstract

The invention discloses a multi-parameter uncertainty analysis method based on a value set visualization technology. The multi-parameter uncertainty analysis method comprises the following steps: 1, constructing a value set function in a complex form based on a known analytical expression; 2, quickly drawing a corresponding value set graph and a parameter action arrow by utilizing a value set function; 3, selecting key parameters, and drawing a discrete value set and a parameter action arrow; and 4, completing multi-parameter uncertainty problem analysis according to the coverage range and themoving trend of the value set and the action arrows of the parameters. When solving the problem of multiple uncertain parameters, the multi-parameter uncertainty analysis method based on a value setvisualization technology, on the basis of a value set mapping mathematical theory and in combination with a value set rapid drawing skill, provides a visual expression image to clearly present the effect of each parameter on an output result, and corresponding analysis results can rapidly and visually reveal different influences of multiple parameters on the output result, and then optimal parameter configuration is found, and the output result is improved.

Description

technical field [0001] The invention relates to the technical field of numerical calculation, in particular to a multi-parameter uncertainty analysis method based on value set visualization technology. Background technique [0002] The numerical integration method adopted by the numerical calculation software can simulate the switching, limiting and other operations of components in time series, and give a response curve to describe the dynamic response characteristics of the system under certain parameter combinations. However, it is difficult to be directly applied to some systems containing multiple uncertain parameters, because the calculation workload increases sharply with the increase of the number of parameters according to the law of permutation and combination. At the same time, there is a lack of accurate and convenient methods for the coordination and tuning of parameters among various components in the system, and it mostly relies on empirical conclusions and la...
