基于DEVS的BOM组件与仿真引擎研究   总被引:1,自引:1,他引:0  
在组件化建模与仿真领域内,基于BOM规范的KD-XSRFrame组件建模与仿真框架得到了广泛的应用,但是以离散时间仿真为手段的设计模式使得由BOM组件构成的仿真系统性能不高。因此,如何提高运行效率成为基于BOM的组件式建模与仿真必须解决的问题。根据现有组件系统的不足,引入离散事件的概念重新设计了BOM组件模型和仿真引擎,提出了基于离散事件系统规范的BOM组件建模框架,实现了以事件为中心的仿真引擎。测试结果表明该系统能有效地减少模型调用和引擎工作的开销,显著地提升了整个仿真系统的运行性能。
Abstract:
In the field of MS of Component, the modeling and simulation framework based-on Basic Object Model (BOM) named KD-XSRFrame has been used widely, but its performance is inefficient for the design basis of discrete time. And the key issue in BOM component MS is how to improve the performance of simulation application. The deficiencies of legacy system was profoundly discussed, the BOM component and its engine were reengineered by using the concept of discrete event, a new modeling framework of BOM base-on Discrete Event System Specification was put forward, and a new engine was designed which focused on events. The experiment shows that the BOM component and engine of discrete event can sharply decrease the spending of model function calling and time advancing, and greatly improves the performance of simulation application system.  相似文献

基于MDA的两层HLA技术研究   总被引:1,自引:1,他引:0  
HLA缺乏由仿真模型构建联邦成员的统一开发框架,所有联邦成员均是平等的,即体系结构是一种平面关系,联邦成员级的模型重用仍然是一种静态重用,无法实现模型动态加入不同FOM的联邦。提出了一种基于MDA的两层HLA框架FIA/FEI,首先将MDA引入HLA仿真建模,给出了MDA和HLA融合的途径。继而提出了突破了现有HLA的平面结构的资源管理联邦的思想,以支持对元模型的管理和基于元模型的仿真应用联邦的动态组合和FOM信息的动态配置,实现基于元模型的资源重用与共享,提高了HLA的模型资源动态重用与共享能力,应用实例验证了该框架的可行性。
Abstract:
HLA has not HLA uniformed modeling frame for constructing federates from general simulation models, and its all of federates are au pair, i.e. it is planar architecture essentially, so related models are difficult to enter the federations with different FOM dynamically. As a result, model reusing in federate level is static reusing. MDA based HLA with two levels frame (FIA/FEI) was proposed. At first, the schema of MDA integrated HLA was discussed, then the resource management federate was specified, which broke through the plane architecture of existing HLA and supports the management of meta-models, dynamic configuration of FOM information, and dynamic creation of simulation application federate based on meta-models. This two level frame realizes meta-model based resource reusing and sharing, improving the reusing ability and sharing ability of the model resources for HLA. The application practice verifies the feasibility of double level frame.  相似文献
