摘　　要：实体是仿真系统的基本单元,实体建模与仿真的主要对象是实体的属性信息。在分析了现有实体建模与仿真工具中存在的问题之后,提出了一种能够方便各类用户对实体进行建模与仿真的方法。该方法解决了实体属性描述和扩展的问题,同时通过该方法建立的仿真程序具有很好的移植性和扩展性。结合提出的实体概念模型和仿真系统的概念模型,利用实体属性的数据映射和语义屏蔽的思想从理论上论述了该方法的正确性,同时通过建立实体建模与仿真工具从实际应用上验证了该方法的可行性。Entity is the essential cell of the simulating system, and the main content of modeling and simulating entity is attributes of entity. By analyzing the problems in the modeling and simulating tools, a method used expediently to model and simulate entity by each user was proposed.The method resolved the problem of description and extending attributes, and also the simulating programs using this method have favorable transplantation and extendibility. The exactness of the method was proved on the aspect of theory through data mapping and semantic screening based on the entity conceptual model and simulating system conceptual model. In addition, the feasibility of it was also approved by application of the practical tools.
