The Research On The Method Of Credibility Assessment Of Virtual Experiment Simulation System

Recently, as the simulation technology develops deeper and deeper continuously and widen its application domain endlessly, people pay more and more attention to the research on credibility of simulation system. Whether a simulation system is usable for a certain project directly affects applications and decisions forward determined by the simulation system. The Simulation result can not make any sense in the practical application, unless the validity and credibility are assured. Therefore, how to evaluate the credibility of a simulation system is the most important in the areas of simulation technology.First, by researching the significance and background of the credibility of simulation system, the basic theory of simulation credibility has been deeply discussed, and several key problems have been pointed out. Second, we have a detailed analysis and contrast among traditional methods of credibility assessment, taking the method of evaluation tree, arrangement analysis method, and dark assessment for example. Third, an improved method of assessing the credibility of simulation system, which is called process evaluation and faces the process of simulation, is brought forward. This new method includes the thought of delaminating as an advantage and fetches up the disadvantages which can make the error cumulate and greatly rely on assessment person, so it increases the precision of the assessment result of simulation system.Taking the virtual experiment simulation system of computer principle for validating subject, process evaluation is validated. Through the analysis and contrast between process evaluation and traditional assessing method, it can be discovered easily that process evaluation has obvious advantages for improving a simulation system. Finally, a summing-up to all the fruit done is advanced, and suggestions for further research are also put forward.
