文章根據ERP 系統的特點，提出在系統設計階段，采用形式化標記語言——Z 語言對系統框架進行精確描述，以期提高系統構建的可靠性，降低開發風險，減少維護成本。文中根據三層框架結構，分層描述了公共對象層，業務處理層和調度層的狀態模式和操作模式，為框架的實現提供了理論保障。

The Design of an ERP Framework Based on Z Language Xu Xiangying1 Yang Hebiao2 (1.Information Engineering College of Yangzhou University, Yangzhou, Jiangsu province, China,225009;2.School of Computer Science and Telecommunication Engineering, Jiangsu University,Zhenjiang, Jiangsu province, China,212013) Abstract：According to the features of ERP systems, a formal specification notation—Z language is used in the design stage of the system in this article to describe the system’s f ramework accurately. It expects to improve the system’s reliability, decrease the developing risk and reduce the maintenance cost. The article presented state models and operation models of the three tiers architecture: common object tier, business model tier and function selection tier respectively. It provided a theoretical guarantee for the implementation of the framework.
