摘　　要：为了有效地解决大型复杂仿真系统的可信度量化问题,分析影响大型复杂仿真系统可信度的各方面因素,建立了其可信度评估指标体系;考虑到大型复杂仿真系统可信度评估涉及大量不同层次、不同粒度的定性指标,使用层次语言变量来尽可能准确的获取其评估信息,并使用二元语义分析方法来处理这些多个来源、多种粒度的评估信息,从而有效地实现大型复杂仿真系统的可信度量化。实际应用证明了该量化方法的有效性。Based on the analysis of factors affecting credibility of large complex simulation systems, a credibility index system was given. Because credibility evaluation of large complex simulation systems involves lots of qualitative indices with multiple levels and granularities, hierarchical linguistic variables were used to acquire their evaluation information, and the two-tuple hnguistic method was used to deal with the evaluation information with multiple sources and granularities, and the credibility quantification of large complex simulation systems was implemented. Practical applications proved that this quantification method is effective.
