Abstract


, System simulation activities around the simulation model, and therefore adapt to the user application purposes under the premise, the quality of the simulation model to a large extent affect the confidence of the judgment of the people for the real object behavior and availability of simulation results. Model VV A activity is to ensure the quality of the model and an effective way to assess its credibility. The model validation is an important part of the model VV A activities. Model validation, data consistency analysis method is often used and very effective means. This paper focuses on data consistency analysis methods conducted in-depth research, mainly from three aspects. The model validation First built according to the user the purpose of the index system, and then around the index system for the implementation of the verification, and analysis of the underlying index system node is often used data consistency analysis method. People have done a lot of research, the success of a variety of data consistency analysis methods applied to the field of model validation. However, has not yet formed a complete set of data analysis programs. Analysis program proposed will improve the model validation efficiency and accuracy of analytical results, to reduce the workload of the analysts. To solve this problem, this paper goal, to try to cover the various situations encountered in the data analysis and gives a data analysis programs. Model validation not only can guarantee the quality of the model, it is the basis of the model credibility evaluation. Credibility evaluation model commonly used index system model validation, data analysis results by the underlying node began to transform, transformation and integration of results up layer by layer, and eventually come to the value of the root node, the value is reflected in the model and the real object The degree of consistency is an important part of Credits. This article Name the value \Underlying node analysis is usually the type of data consistency analysis method, and therefore the analysis result is not in the same scale space, can not be directly fused. To solve this problem, this paper and gives the algorithm used to convert the above-mentioned five analytical methods. Data consistency analysis requires a large number of calculations, which requires the model validation have sufficient knowledge reserves. In order to improve the efficiency and accuracy of the data analysis, design and development model validation based on data consistency analysis tools. The tool in the Windows operating system, the the VC6.0 compiler platform development is complete.
