Guided Simulation System Vv & A Of The Theory, Methods And Software Tools

In this paper, Firstly, the concept and purport of VV&A are briefly introduced, the factors which influence the creditability of Guidance Simulation System are researched, then a VV&A decision-making method is advanced, which integrates the whole factors to evaluate the credit- ability of Guidance Simulation System.Secondly, the methods for consistence test have been deeply researched are summarized and introduced. As for the methods for static consistence test, rank sum test which belongs to the static consistence test of small sample is emphasized; As for the methods for dynamic consistence test, Fourier spectrum, and maximum entropy spectrum estimation are respectively introduced. The new researched methods are analyzed, which include Wigner distribution, the spectrum estimation for multidimensional time series and Higher-Order spectrum estimation.Thirdly, the contents analyze the advantage and shortage of the software which was developed earlier, and develop a new software for consistence test with reworking the old one; Another software is developed, which is for estimating the creditability of a certain Guidance Simulation System. And the design and How-to of this software is particular narrated.Finally, using this two software tools, the creditability of a certain Guidance Simulation System is estimated. The processes of decision-making and estimation is particular described.
