Problems solved by technology

This method can make full use of expert experience, but it does not fully meet the requirements
Specifically, first of all, the existing methods rely on expert experience, whether they use scoring or other quantitative means, they are qualitative assessments in nature and lack effective quantitative analysis support
At the same time, since the review experts participating in different stages are often different, it is difficult to guarantee the consistency of the review results, which affects the objectivity of the evaluation conclusions
Secondly, it is difficult for existing methods to effectively use authoritative models or experimental data, and the evaluation conclusions obtained by comparative analysis based on authoritative models or experimental data are obviously more convincing

Embodiment Construction

[0019] The invention provides a method for quantitatively evaluating the credibility of a simulation model, such as figure 1 shown, including the following steps:

[0020] Step 1, determine the simulation model set {Model 1 , Model 2 ,...Model m}.

[0021] Step 2, select the simulation model Model to be evaluated 1 .

[0022] Step 3, determine the I / O set {(I / O) for comparative analysis 1}. The I / O set should be able to cover the core capabilities of the model and can be supplemented by expert review.

Abstract

The invention discloses a method for quantitatively evaluating reliability of a simulation model. The method comprises the steps of: 10, determining a simulation model set to be evaluated; 20, determining an experimental data I / O set of the simulation model to be evaluated; 30, defining an input set and an output set of the experimental data I / O set; 40, using the input set of the experimental data I / O set as an input set of the simulation model to be evaluated to obtain an output set of the simulation model to be evaluated; and 50, figuring the reliability of the simulation model to be evaluated according to the output set of the simulation model to be evaluated and the output set of the experimental data I / O set. The invention can realize the reliability quantitative evaluation of the simulation model, effectively reduces the decision risk made based on the simulation, and provides the basis for the optimization design of the simulation model.

Description

technical field [0001] The invention relates to the field of computer simulation, in particular to a method for quantitatively evaluating the credibility of a simulation model. Background technique [0002] With the deepening of simulation applications, reliability has become the most important indicator for people to evaluate the quality of simulation systems, and simulation without sufficient reliability is meaningless. As the core of the simulation system, the credibility of the simulation model has also become the fundamental factor that restricts the credibility of the simulation results. The evaluation of the credibility of the simulation model has become the focus of concern and research in the simulation field. [0003] At present, in terms of the credibility evaluation of simulation models, the main research results are concentrated on the model VV&A. Its core is to carry out standardized control over the whole modeling process, conduct expert review on the basis o...
