摘　　要：针对集团企业大型装备虚拟采办应用中,存在多层次、多方位的模型异构性,以及已有大量专业沉淀,需要提高模型的可重用性和可组合性水平的问题,本文基于一种复杂异构系统统一建模的理论框架,给出复杂异构系统统一建模方法的形式化定义,从可信度分析的角度探讨统一建模方法的自洽性,并从工程化的角度提出统一建模方法的实现方式及其文本描述规范。最后,以某装备虚拟采办为背景,对本文所提出的统一建模方法进行应用验证。结果表明,所提出的统一建模方法可有效支持在集团企业开展大型装备的虚拟采办。To improve the levels of the reusability and the combination of models for the problems that there are multiqevels and multi-types of heterogeneity from a large number of legacy models in the group enterprise application of simulation based acquisition （SBA）, the formalism of an unified modeling method of complex her erogeneous system is proposed based on a meta modeling framework （M2F）, and the feature of self-consistency for the unified modeling method is derived based on credibility theory. Furthermore, an engineering approach and text specification for the unified modeling method are given. Finally, a case study of the SBA for the large equipment indicates the effectiveness of the proposed unified modeling method.
