摘要
Tropos模型没有考虑需求风险分析.为了分析需求风险，本文介绍了一种基于Tropos模型的需求风险分析方法.该方法提出了基于Tropos目标图的需求关系框架,并以此为基础识别和分析需求的风险因素：干系人,环境,技术,和需求复杂度,最终获得需求的可行性风险.由于其主观性,这些风险因素通过相关专家打分来获得风险值.本文通过列车系统部分功能的实际应用说明该方法的使用过程，以及其能够在需求过程中及时发现存在风险的干系人和需求.这样就能较早地解决风险,节省项目成本.
Risk of requirement is ignored in Tropos model. To analysis risks and relationships of requirements, a method ana- lyzing risks in requirement phase is introduced. It＇ s on the base of Tropos model, and proposes a Tropos goal gram-based framework of requirement relationship to identify risk factors of requirements： stakeholder, environment, technology and complexity of require- ment and assess risk about feasibility of requirements. Because of subjectivity, these risk factors are assessed by relative experts. It is proved by an example of train sub-system that the method can identify stakeholders and requirement with risk in time. This makes it earlier to solve risks and saves cost of project.
