面向复杂体系仿真系统的可信度评估指标构建方法

Methodology Used to Construct Credibility Assessment Index for Simulation System of Complex System of Systems

针对传统的单树状指标体系难以全面深入地表征可信度,尤其是体系内部系统之间的互操作关系,提出一种混合式的评估指标体系。首先建立一种共性的评估指标知识库,可在一定范围内根据不同的应用领域进行裁剪;在此基础上,从体系功能、运行效能、技术体制3方面构建多维度的评估指标体系主体,并基于仿真试验数据挖掘指标间的关联关系,构建该关联关系的可信度评估方法,最终结合两者形成动态网络化的指标体系。该混合式指标体系构建方法可为复杂体系仿真系统的可信度评估技术研究提供参考。

Since the traditional single tree index can not fully describe credibility of system of systems,especially when there are interoperation relationships within it,we have proposed a new hybrid index system construction methodology.We first establish a common evaluation index library,which within certain range,can be tailored according to the different application area.Using this as a base,we construct a multi-dimension assessment index system from the views of system function,operation effect and technique architecture.Based on simulation experiment data,we can mine the interoperation relationships among existing indexes,and construct a credibility assessment method for these relationships to establish the dynamic and networked index system.This hybrid index system construction methodology can build reference and support for research on credibility assessment for simulation system of complex system of systems.
