Abstract: The expression model of viewpoint in multiviews-oriented requirements engineering is related to the acquisition and description of requirements information closely, and directly influence the consistency checking and integration of viewpoints. Based on the recent research progress and fruit of software requirements engineering, a new expression model of viewpoint based on problem frame is proposed and its characteristics and application are presented through a case study. Practice shows the model has availability and operability.

Key words: requirements engineering, viewpoint, problem frame, expression model of viewpoint

摘要： 在多视点需求工程中，视点表示模型与视点需求信息的获取、描述密切相关，影响着后阶段视点一致性的检查和集成。鉴于需求工程领域的发展，该文提出了一种基于问题框架的视点表示模型，展示了该模型的特点及应用。实践表明，该模型具有实用性和可操作性。
