【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。
[Abstract]:In recent years, with the development of embedded technology, products based on embedded system can be seen everywhere. Whether the system project can be completed on time has become an important problem to be solved. Because of the uniqueness and uncertainty of the embedded system development process, how to evaluate the requirement risk of the project is an important and difficult point. In the development cycle of the project, the time to find the problem is proportional to the cost of fixing the problem. The earlier the problem is discovered, the lower the cost of fixing the problem, and the requirement phase is the first phase of project implementation. If we can evaluate the risk of the project in the requirement stage and make corresponding measures to avoid the risk, then we can ensure the completion of the project on time and quality to the maximum extent. However, at present, the requirements risk assessment method for embedded system can be applied in a single way, and it needs to be studied deeply in evaluating the demand risk of embedded system project in a comprehensive and effective way. Based on the introduction of the development process and characteristics of embedded system, this paper combines the research on the causes of requirement risk and multiplying effect, aiming at the problem that the embedded system project is delayed because of the requirement risk under the specific development environment. In this paper, the requirement risk assessment index system of embedded system project is constructed, and the application of requirement risk assessment method based on fuzzy analytic hierarchy process is put forward on the basis of this index system. It realizes the comprehensive and effective evaluation of embedded system project demand risk. This paper applies the index system and the risk assessment method to the Aimer37 project of a company, and further verifies the usability of the evaluation index system and the risk assessment method.
