Abstract

The invention discloses a simulation and test result consistency analysis system and method, and relates to the field of computer simulation analysis application. Through the system and the method, the consistency of batch simulation results and test results can be quickly analyzed, and further the credibility of a simulation model is assessed; and meanwhile, based on the system and the method, test point arrangement can be performed based on the simulation model, values of existing test data are fully mined, simulation model correction is performed based on consistency analysis result guidance, the technical level and the pre-test capability of simulation analysis are gradually improved, effective combination of ''test guidance by simulation and simulation confirmation by test'' is trulyrealized, and repetition of structure design is avoided.

Description

technical field [0001] The invention relates to the application field of computer simulation analysis, in particular to a simulation and test result consistency analysis system and method. Background technique [0002] The simulation system is a system that uses a simulation model to replace the researched object, and conducts experiments on a computer or in an environment composed of other simulation equipment. Whether the simulation model is accurate or not can be attributed to the category of simulation system credibility (Credibility) evaluation. The evaluation of credibility must be solved through VV&A (Verification, Validation & Accreditation, verification, confirmation and release) activities. [0003] VV&A activities include three parts: model verification, model validation, and model release. Model validation is an important part of VV&A activities. Its task is to ensure that a correct model is established, which can improve the similarity between the model and the ...
