【摘要】 近年来，随着嵌入式技术的不断发展，基于嵌入式系统的产品随处可见。系统项目能否按时保质的完成就成为了要解决的重要问题。由于嵌入式系统开发过程的独特性和不确定性，如何评估项目的需求风险是一个重点也是一个难点。在项目的开发周期中，发现问题的时间与修复问题所花费的成本是成正比的。发现问题越早，那么修复问题的成本就越低，而需求阶段恰恰是项目实施的第一个阶段。如果能在需求阶段评估出项目的风险并针对风险制定相应的措施进行规避，那么就能在最大程度上保证项目按时保质的完成。但是目前针对嵌入式系统的可具体应用的需求风险评估方法还都比较单一，在全面有效的评估嵌入式系统项目的需求风险上还需要不断的深入研究。本文在介绍了嵌入式系统的开发过程和开发特点的基础上结合及需求风险的成因和倍增效应研究，针对嵌入式系统项目在特定的开发环境下因为需求风险导致项目延期的问题，研究构建了嵌入式系统项目的需求风险评估指标体系，并在此指标体系的基础上提出了基于模糊层次分析法的需求风险评估方法的应用，实现了对嵌入式系统项目需求风险的全面有效的评估。文章通过对某公司的Aimer37项目运用了该指评估标体系和风险评估方法，进一步验证了评标指标体系和风险评估方法的可用性。更多还原

【Abstract】 In recent years, the technology of embeded system is developing fast and embeddedproducts appear in many fields. Because the Uniqueness and Uncertainty which exists int thedeveloping period of embeded system, Assessment of risk of embeded system project hasbecome a difficult and important problem. Inside the Project development cycle, the earlierto frind where the problem is, the better to reduce the project cost. Requirements phase is theearlist phase in the project development cycle, if we can asses the risk in the requirementsphase,and take measures to avoid this risk,that sholud provide great Guarantee about finishthe project on time. However, Specify method to asses the requirements rist in this days, isstill inadequate, The way to Comprehensively assese the rist of requirements in embededsystem project need further research.This dissertation intuoduced the development features and process, discussed the resonof requirements rist and its Multiplier effect. On the face of project delays problems whichcaused by requirements on certain develop enviroment, this dissertation built the indicatorsystem of requirements analysis risk, further more, this article find a requirements rist assesmethod which based on fuzzy Analytic Hierarchy Process. On the last Chapter, tis dissertationuse the research and method in the real operation of a Aimer37project from a company,which verified the Practicality of the the indicator system and method,更多还原
