Storage and Retrieval of Business Process Simulation Models Based on IDEF3

模型的集成和重用是提高仿真建模效率的有效方法,而模型的存储和获取是实现模型集成和重用的关键技术.在研究基于IDEF3的业务过程仿真建模的基础上,分析设计了相应的数据库概念模型,实现了仿真模型在关系数据库中的存储及与描述模型在数据上的共享和集成.然后,重点研究了如何通过结构化参数化的查询从模型库中获取用户想要的特定仿真模型,提出了综合考虑模型基本元素、基本模块、基本属性和整体结构的计算仿真模型相似性的算法,并开发了相应的支持软件工具.

The integration and rouse of models are the effective means to improve the efficiency of simulation modeling. Storage and retrieval of the models are the key technologies of integrating and reusing models. With investigating the methods of business process simulation modeling based on IDEF3, a database conception model was analyzed and designed so that the simulation models can be storod in a relational database and shared with mapping models. The methods how to retrieve a specific business process simulation model based on IDEF3 from a database was studied. A numerical algorithm for calculating simulation model similarity is proposed in which the basic elements, basic modules and total structure are taken into account synthetically. Finally, a supporting software package was developed.
