中文摘要：

重用已有模型构建新的仿真应用一直受到系统仿真领域的关注。基于模型数据库搜索、判断与应用需求相匹配的仿真模型资源是实现重用的关键问题。提出一个基于概念模型语义描述的仿真模型资源搜索框架,详细说明了该搜索框架的结构。框架建立了由实体、任务、交互等概念模型元素构成的仿真模型资源语义描述模型,采用本体语义和关键字匹配等搜索策略。模拟实验表明该框架可以很大程度上提高搜索判断的准确性。

英文摘要：

Constructing new simulation applications based on the reuse of existing simulation models has always been paid attention in the system simulation field.It is a key issue in realising the reuse that to search,estimate and apply the simulation model resources matching the needs of application based on the database.This paper proposed a search framework for simulation model resources based on semantics description of conceptual model,and its structure is expounded as well.The framework sets up a semantics description model for simulation model resources constructed by the conceptual model elements of entities,tasks and interactions,and uses searching policies of ontology semantics and
