摘　　要：采用面向服务的仿真体系,构建基于组件技术的仿真模型体系,有效提高仿真活动的灵活性和效率。以J2EE/EJB技术规范为基础,建立潜艇战/反潜战建模与仿真EJB组件体系结构,包括仿真应用层、基于J2EE的仿真服务层和数据库资源层。以反潜直升机仿真组件为例,以其功能为基础,采用统一建模语言UML设计其顶层静态类结构,并分析该结构包含的聚合和依赖两类关系。对仿真组件的有状态EJB和无状态EJB进行了分类,并设计了组件实现的接口类和实现类。从仿真应用的角度设计了EJB组件的访问控制机制,包括服务器本地访问控制机制和客户端远程访问控制机制。The agility and efficiency of simulation was improved effectively through constructing model system based on bean technology with service-oriented simulation architecture. On the basis of J2EE/EJB technology specification, EJB architecture of submarine and anti-submarine warfare M＆S was composed including simulation application layer, simulation service layer based on J2 EE and database resource layer. Taking the anti-submarine helicopter simulation bean with its function as an example, its summit static class structure was designed in UML modelling language and aggregation relationship and dependability relationship were analyzed. Stateful and stateless EJB were classified and the interface class and implementation class of bean achievement were designed. From the view of simulation application, EJB access ＆ control mechanism were designed including server local access ＆ control mechanism and client remote access ＆ control mechanism.
