Research on validation method for complex simulation systems

Complex simulation systems have a great many of random or uncertain factors, which make validation of them quite difficult. To solve this problem, a validation method of complex simulation systems is presented. The sensitivity analysis technique is used to determine the effect degree and trend of input variables to output variable of simulation systems. The error analysis technique is used to determine the error ranges of key input variables of simulation systems and validate the interoperability of simulation models. According to the results of sensitivity analysis and error analysis, consistency analysis is performed on the simulation systems, and the validation of complex simulation systems is realized.
