HLA联邦成员中模型的重用性研究

在基于联邦成员级的传统联邦开发模式基础上，从模型的重用性角度，提出了基于模型级的联邦开发新模式；通过改造现有传统联邦成员结构，把联邦成员的不变部分封装成联邦成员中间件，实现模型可以在联邦成员中即插即用，提高模型的重用性和互操作性。     

面向组件的仿真系统构建方法研究

随着软件组件技术的不断发展,基于组件的软件开发方法在仿真领域逐渐被接受,特别是基于分布式的仿真软件开发。SISO（仿真互操作标准组织）提出的BOM（基本对象模型）通过标准化规范描述面向组件的仿真模型,为构建具有可扩展、可组合和可互操作的仿真系统提供了面向组件的实现技术。首先,描述BOM的模板结构及其体系结构,设计基于BOM的仿真模型组件结构,分析这种结构的仿真模型组件间的互操作性;接着从概念层次、联邦成员层次和联邦层次三个不同层次提出面向组件的仿真系统构建方法;最后讨论一种通用的仿真运行框架,通过组合不同的仿真模型组件实现仿真系统的快速构建。

Abstract：

With the development of the software component technique, the components based software development method is accepted in the simulation domain and specifically in the distributed simulation’s software development. The standard of Base Object Model （BOM） developed by SISO （Simulation Interoperability and Standard Organization） is the component-oriented specification of simulation models which gives a component-oriented technique to construct extensible composable and interoperable simulation systems. Firstly, the template and architecture of BOM were described based on which the structure of simulation model components were designed and the interoperation between them were analyzed; Secondly, the processes for constructing simulation systems were argued from the concept level and the federate level to the federation level; Lastly, by composing various of simulation model components, the general simulation running framework which was argued provided component-oriented capabilities to rapidly building simulation systems.     

突发事件下多目标应急救援物资配送路径规划

突发事件发生后,选择最优应急救援物资配送路径提高物资配送的效率和效果,是应急决策者面临的主要问题。以最小化最晚车辆服务结束时间来提高物资配送的效率,以最小化需求未满足率来保证配送公平性,从而达到良好的配送效果。在配送中心唯一的情况下,考虑道路对车型限制、道路阻断修复和道路可靠性对路径的影响,建立多目标应急救援物资配送路径优化模型。设计优先邻点交叉算子来改进基于非支配解排序的遗传算法,提高了局部搜索能力和收敛速度,通过仿真实验验证了算法和模型的有效性,为决策者选择合适的车辆配送路径提供辅助决策作用。
