云仿真系统可信度评估问题探讨

云仿真平台支持“云仿真”模式，能够自动查找仿真资源、动态构建云仿真系统。由于云仿真平台具有按需构建仿真服务、多粒度资源共享等特点，云仿真系统的可信度评估工作在仿真资源的可信度、仿真子系统的可信度、仿真运行环境的可靠性等方面面临新的问题。从云仿真系统全生命周期角度，建立了云仿真系统的可信度评估过程模型和云仿真系统可信度评估指标体系，并给出了一种仿真资源排序评估方法，为云仿真系统可信度评估工作提供参考。

Research on Credibility Assessment of Cloud Simulation System

The cloud simulation platform supports the "cloud simulation" mode, which can automatically find simulation resources and dynamically build the cloud simulation system. Because the cloud simulation platform has the characteristics of simulation services establishment on demand and multi-granularity resources sharing, the credibility evaluation of the cloud simulation system faces new challenges in the credibility of the simulation resources, the credibility of the simulation subsystems and the reliability of the simulation environment, etc. From the whole life cycle perspective of the cloud simulation system, the credibility evaluation process model and the credibility evaluation index system of the cloud simulation system are established respectively and a ranking assessment method for choosing the simulation resources is proposed, which could provide reference for the future credibility evaluation of the cloud simulation system.
