摘要

DEVS建模和仿真(M&S)有多种计算机语言实现，如java, c#或c++。因此，需要一个分布式平台来为仿真提供互操作性机制，并鼓励遗留仿真的可重用性和多种DEVS模型的集成。在本文中，我们在DEVS/SOA的更新版本中应用了最近提出的DEVS M&S互操作性标准。这个面向web的框架的主要目标是以透明、开放和可扩展的方式连接异构的DEVS模拟元素。我们定义了一个DEVS/SOA实现，它在WSDL标准中体现了面向服务的体系结构(SOA)，以描述模拟器和协调器接口以及SOAP标准，以支持它们之间的通信操作。这种安排允许前端用户应用程序在没有本地访问建模组件的情况下进行模拟。此外，我们还举例说明了一个真实的基于军事的基于Java和。net的DEVS模型的DEVS仿真互操作性的例子。两个不同示例的实验表明，当使用DEVS/SOA进行分布式仿真时，我们获得了平均22%的加速提升。

DEVS/SOA: Towards DEVS Interoperability in Distributed M&S

DEVS Modeling and Simulation (M&S) has multiple implementations with several computer languages such asJava, C# or C++. Therefore emerges the need of a distributed platform to provide interoperability mechanics for simulationand encourage reusability of legacy simulations and integration of diversified DEVS models. In this paper, we apply a recentlyproposed interoperability standard for DEVS M&S throughout a renewed version of DEVS/SOA. The main goal of thisweb oriented framework is to connect heterogeneous DEVS simulation elements in a transparent, open, and scalable way.We define a DEVS/SOA implementation that embodies Service Oriented Architecture (SOA) within WSDL standard to describethe simulator and coordinator interfaces and SOAP standard to support communication operations between them. This arrangementallows frontend user applications to lead simulations without local access to modeling components. Furthermore, weillustrate a real military based example of DEVS simulation interoperability among Java and .NET based DEVS models.Experiments in two different examples show that when the simulation is distributed using DEVS/SOA, we obtain a speedup of 22% in average.
