基于泛关系模型表示的层次化模型管理框架

针对常见模型表示方法缺少对多阶段建模过程支持,造成不同建模阶段模型难以统一管理、共享和重用的问题,提出基于泛关系模型表示的层次化模型管理框架。分析现有模型表示方法特点和多阶段建模过程中模型表示及管理需求,采用泛关系模型表示建立概念模型和数学模型表示方法之间映射关系,建立一体化模型表示方法和层次化模型管理框架; 研究层次化模型管理框架中概念层模型和泛关系层模型的模型库设计逻辑,并基于泛关系理论,研究了物理层模型的动态生成方法,实现了不同建模阶段模型的一体化表示和统一管理。

Hierarchical model management framework based on universal relation model representation

The exiting model representation cannot meet the requirements of multistage modeling, so model share, reuse and management can hardly achieve in multistage modeling process. Therefore, a hierarchical model management framework based on universal relation model presentation was presented. Firstly, the requirements of model representation in model management and the limitations of exiting model representation were analyzed, then a model representation based on universal relation was investigated to set the mapping relation between layers of conceptual model and mathematical model, and the integrative model representation and the hierarchical model management framework including conceptual model, mathematical model and physical model were set up. At last, the logic of modelbase in management framework was designed and the physical model generation based on universal relation was investigated. The model of different modeling process could be managed uniformly based on an integrative model representation.
