摘要

<FONT face=Verdana>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.

Abstract

<FONT face=Verdana><FONT face=Verdana>Risk of requirement is ignored in Tropos model.To analysis risks and relationships of requirements

a method analyzing 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 requirement and assess risk about feasibility of requirements.Because of subjectivity

these risk factors are assessed by relative experts.It is proved by nexample 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.
