摘要: 软件框架需要在领域内不同的应用环境中使用,因此框架的适应性是其非常重要的质量属性.将反射技术引入建模与仿真领域,通过将支持大规模分布交互仿真系统开发的软件框架进行体系结构级的反射,解决了系统结构动态演化和运行时扩展问题;通过对仿真模型进行组件或对象级的反射,解决了模型的动态表示和行为演化问题.通过将反射塔构造为一个数据仓库对反射模型进行集中管理和统一接口访问,使系统在体系结构模式上表现为以数据仓库为中心,改善了反射系统的安全性,同时提出了一种新的基于反射数据库的软件设计模式.利用RTI的服务去维护分布的仿真节点的反射数据库,简化了系统的实现,同时也封装了RTI,从而构造了一个比HLA更高级和友好的分布计算和仿真环境,为仿真应用系统的快速开发提供了强有力的支持.

Abstract:  Adaptability is one of the most important qualities of the software frameworks, for which are used in various applications of a field. Reflection was introduced to improve the adaptability and support re-configuration of a modeling and simulation framework for the development of large scale simulation systems. Through the reflection of architecture of the framework, the framework supported architectural evolution and re-configuration in run time. Through the reflection of context of the simulation component or object models, the models supported dynamic representation and behavioral evolution. By organizing the reflective information into memory database which was maintained by HLA/RTI, the system was repository-centered architecturally. As a result, security of the reflective system was improved and a new design pattern based on the reflective database was presented. On the other hand, the interface of RTI was encapsulated, so a more advanced distributed computing environment and simulation engine with friendly interface was provided, which could support the development of applications rapidly and strongly.
