The Simulation Confidence Level Measurement Method Research

While the application area of simulation system is becoming more and more wide, which is the result of the development of simulation technology and the increases of simulation requirements, the simulation system is becoming more and more complex. As the importance of simulation system is understood and accepted, People are always suspicious of the effectiveness of simulation system. In the point of view of the users of simulation system or in the point of view of applications of simulation system, there always exists the requirement of evaluation methods of the effectiveness of simulation system. The study of method of simulation system confidence is based on these requirements.The paper studies the methods of measurement used in the simulation confidence, sets up the conceptual framework and the process model of simulation confidence, presents the methods which are use to confirm the requirements of simulation confidence, set up measurement architecture and achieve the framework, provides the evaluation performance of measurement methods of simulation confidence and an application example of it.The innovative work is mainly included in the following three aspects:1. the staged division of measurement:the procedure of measurement of simulation confidence is divided into three stages which includes the setup of requirements of measurement, the setup of measurement architecture and the achievement of measurement framework.The staged division shows the intrinsic consistence of the procedure achieved by different measuring methods of simulation confidence, shields the distinction of the procedure achieved by different measuring methods of simulation confidence, stresses the whole requirements of the procedure, and unites the descriptive specification of the procedure of different measuring methods of simulation confidence.2. the level division of measurement attributes:The level division makes clear the division prerequisites of measurement requirements, optimizes the achievement methods of dividing measurement requirements, decrease the subjective factors of the division. Thus the division decreases the performing difficulties in the division of measurement requirements and provides an effective way to divide the measurement requirements.3. the virtual computation of weighted value:the computing procedure of weighted values is divided into two parts which are the computation of inner weighted-values and the computation of outer weighted-values respectively.The procedure decreases the dependence of expertise, simplifies the importance evaluation of weighted values, which leads to the decrease of difficulty in analyzing and computing the weighted values and the optimization of the way to analyze and compute the weighted values.
