Abstract: Aiming at the disadvantage of interoperation of High Level Architecture (HLA) based distributed simulation lacking ability to overcome semantic conflict, a method of semantic interoperation in HLA distributed simulation based on multi-view nesting ontology-mapping was proposed. Current HLA/Federation Object Model (FOM) mechanism was improved. The concepts of nesting ontology, multi-view nesting ontology and complanation of nesting ontology were defined. The framework, process and algorithm of multi-view nesting ontology mapping were presented, and the middleware technology supporting semantic interoperation was introduced. This method provided semantic interoperation among federates and promoted intelligence of HLA distributed simulation. A typical simulation example of high speed train's distributed simulation system was used to demonstrate its feasibility and effectiveness.

摘要： 针对高层体系结构分布式仿真互操作难以克服语义冲突的不足，研究并提出基于多视图—嵌套本体映射的高层体系结构语义互操作方法。对现有高层体系结构/联邦对象模型机制进行改进，定义了嵌套本体、多视图—嵌套本体和嵌套本体平面化等概念，阐述了多视图—嵌套本体映射框架和映射算法流程，并介绍了支持语义互操作的中间件技术。该方法可以有效支撑仿真模型与仿真模型间的语义互操作，提高分布式仿真的智能化水平。通过仿真实例，建立了一个典型复杂产品——高速动车组的分布式仿真系统，检验了方法的可行性和有效性。
