支持企业资源计划快速开发的计算无关层全局模型建模

Modeling of global model in computational independent level supporting quick development of ERP

针对目前企业资源计划系统灵活性较差、定制开发实施周期漫长且成本较高的问题,应用模型驱动架构的相关技术和思想,研究了模型驱动的企业资源规划系统快速开发模式。为了优化并快速建立企业业务模型,面向该模式提出了全局模型的概念,由此建立了包括全局模型和业务模型的计算无关层模型结构。在此基础上,重点研究了面向企业资源规划系统快速开发过程的全局模型建模方法。将全局模型分为全局业务分析模型及全局业务模型,并构造成为按层次分解的模型结构,建立了它们的基本模型,定义了基本模型中的元素。最后通过全局业务分析模型和全局业务模型的图形化建模实例验证了上述建模理论的可行性和实用性。

To solve the problems of poor flexibility,long customization development and implementation process,and high cost of Enterprise Resource Planning（ERP）,a quick development mode of ERP system based on Model Driven Architecture（MDA） was studied by applying the theory of MDA.In order to optimize and construct enterprise Business Model（BM） quickly,the concept of Global Model（GM） oriented to this mode was put forward.Then,the structure of computation independent model including BM and GM was constructed and GM modeling method based on the quick development process of ERP was studied in detail.GM,whose structure was divided by layers,included Global Business Analysis Model（GBAM） and Global Business Model（GBM）.The basic model of GM was set up and elements were defined.Finally,graphical modeling examples of GBAM and GBM were constructed in order to validate the practicability and feasibility of proposed modeling theories.
