摘　　要：复杂系统仿真迫切需要能够同时支持多领域分别独立针对性建模和全系统统一集成仿真的方法.将当前用于复杂系统仿真的建模方法分为统一型、组合型和生成式三大类,分析指出生成式建模方法具有较之其它方法的独特优势,有望解决复杂系统仿真建模面临的问题.研究了当前仿真领域应用的各类生成式建模方法存在的不足.提出了以仿真模型可移植性标准(SMP2)为基础,综合利用生成式建模方法的两大流派-模型驱动架构(MDA)和模型集成计算(MIC)-的先进技术和规范,构建复杂系统生成式仿真建模方法的研究思路.分析了其中的多领域生成式仿真模型公共表示规范、各类仿真形式体系到SMP2的映射与模型变换以及面向领域的仿真建模工具的自动生成等三大关键技术问题.设计了生成式仿真建模一体化支撑环境的体系结构,介绍了其中已经完成的工作和下一步的重点.Complex system simulations desire modeling methodologies which support both domain-specific modeling of subsystems and universal integration and simulation of the whole system.Current modeling methodologies for complex system simulations are overviewed and classified as unified,composable and generative ones in the second part.It turns out that the generative modeling methodology possesses additional advantages over others when applied to complex system simulations.The shortcomings of current generative modeling applications in simulation domain are discussed.Based on the new born simulation model representation standard SMP2（simulation model portability standards 2）,we propose a systematic generative simulation modeling methodology.It makes use of the relevant technologies and standards of MDA（model driven architecture） and MIC（model integrated computing）,which are the two main pertinent directions of the generative modeling methodology.Three key technical issues in the road to generative simulation modeling are discussed,including the common generative representation of multi-domain simulation models,the mapping and model transformation of multi-formalisms to SMP2, and the automatic generation of domain specific modeling tools.Finally,the architecture of a schematic supportive environment for generative simulation modeling is put forward;the finished work and next step are also presented.
