StarSim:支持快速构建的离散事件系统通用模拟框架

离散事件系统是研究和实践中常见的一类目标系统,使用软件对其进行模拟是有益甚至必须的。提出支持快速构建的离散事件系统通用模拟框架StarSim,为离散事件系统快速构建软件模拟器。StarSim设计简单通用的系统抽象模型以支持快速构建目标系统模拟器,提供基于事件的实体间交互方式以表达目标系统中的交互行为,引入简化的对象请求代理技术以透明的支持分布性,使用基于令牌分发的多线程技术以并行处理目标系统中同时发生的事件,预留可定制的监测和控制接口以灵活的监控目标系统,使用Java语言编写以确保移植性。为一个混合类型离散事件系统快速构建模拟器,验证了StarSim的诸特性和快速构建能力。

StarSim,Discrete Event System Oriented Generic Simulation Framework Supporting Rapid Construction

Discrete event systemis the most common system type in research and practice.It is beneficial or even necessary to simulate the discrete event systems by software simulators.StarSim,a general simulation framework supporting rapid discrete event system construction was proposed.StarSim designed a simple and general system abstraction model to support rapid construction of the simulator for the target discrete event system.It provided an event-based interaction mechanism to support the interactions between entities in the target system.StarSim introduced the simplified Object Request Broker technique to support the distributiontransparently,and the token-based multi-thread mechanism to handle the simultaneous events concurrently.It provided the customizable probers and monitors for the users to detect and control the target system flexibly.StarSim was implemented by Java,which made it easy to be transplanted.By constructing a simulator for a hybrid discrete event system,the features were illustrated and the rapid construction ability of StarSim was validated.
