摘要
针对复杂系统决策所面临的不确定性问题以及数据的离散性,提出了基于分布式虚拟环境的不确定性问题的协同探索性分析方法。对复杂产品设计方案和数据进行分析和处理,建立了仿真模型,用EONStudio和HLA构建了基于探索性分析的分布式体系结构。最后给出了复杂机构的方案设计实例,用动态仿真协同探索求解系统干涉的问题,对运动特性参数进行了探索性分析,再通过聚类分析得到合理结果。
Targeting to the complicated system decision with facing uncertainty problem and randomicity and discreteness of data, a new method of collaborative exploratory analysis （EA） based on distributed virtual environment for solution to the uncertainty problem was proposed. Firstly, the scheme and data of the complicated product design was analyzed and processed respectively, and the simulation model and the virtual environment was set up. Secondly, the distributed framework ofEON -HLA based on EA was built up with EON Studio and High Level Architecture （HLA）. Thirdly, using the collaborative EA solved the uncertainty problem in the product design in the environment via visualization simulation. Finally, an example for scheme of complex mechanism was given in the environment, which solved the uncertainty interferential problem with collaborative EA and dynamic simulation. The kinematical characteristics parameter of the system was analyzed with EA and clustering method. The result of the application shows that the system is of practicability and validity.
