摘要: 为满足云仿真平台中仿真系统运行环境动态构建过程对仿真资源精确描述的需求,提出一种基于本体案例推理的仿真资源描述的动态管理方法。该方法以案例推理的循环过程为基础,分为仿真案例的描述、适配与推理、修正和扩充,通过抽取仿真任务信息建立基于本体的仿真案例。为了进行仿真案例的匹配,给出案例相似度的计算方法。结合本体案例推理给出了仿真案例推理规则的建立方法;通过监控仿真的实际运行状态修正和扩充仿真案例。结合具体应用给出了仿真案例的描述和推理,说明了该方法的可行性和有效性。

Abstract: To meet the requirement of accurate simulation resource description by technology of simulation system environment dynamically building in Cloud Simulation Platform(CSP), a method of simulation resource description dynamical management based on ontology Case-Based Reasoning(CBR)was presented. Based on the cycle process of CBR, the method was divided into description, adaptation with reasoning, modifying and expansion of simulation cases. Through extracting simulation task information, the simulation case based on ontology was built. To matching the simulation case, the computing method of cases was given. Combined with ontology based case-based reasoning, the method to build simulation case reasoning rule was proposed, and the simulation cases were modified and expanded according to monitoring the status of simulation. The description of simulation case and the ontology-based reasoning rule associated with simulation application were presented to show the feasibility and effectiveness of proposed method.
