摘要
对软件开发效益风险的优化评估,能够有效提升软件开发收益,降低风险概率。对软件开发效益的风险评估,需要确定软件开发效益风险识别的权重,构建软件开发效益风险评估指标体系。传统方法根据各风险因素的重要程度不同,建立重要程度模型,但忽略了构建风险评估指标体系,导致评估精度偏低。提出基于模糊理论的软件开发效益风险评估方法,首先通过分析软件开发效益风险识别需要遵循的原则及软件开发效益风险识别特点,实现软件开发效益风险识别,在此基础上,通过确定软件开发效益风险识别的权重,并利用模糊理论对软件开发过程中成本、进度和质量的风险进行评估,构建软件开发效益风险评估指标体系,从而实现基于模糊理论的软件开发效益风险评估。实验结果表明,所提方法评估的准确度较高,评估的实时性较好,推动了相关课题的研究发展。
This paper presents an evaluation method of benefit risk of software development based on fuzzy theory. Firstly, principles and characteristics of benefit risk of software development are analyzed to realize identification of software development benefits risk. On this basis, fuzzy theory is used to evaluate the cost, schedule and quality risk in software development process through confirming the weight of software development benefit risk identification, and the software development risk benefit evaluation index system is built, so as to realize evaluation of software develop- ment benefit risk based on fuzzy theory. Simulation result shows that the proposed method has high accuracy. The re- al - time evaluation is good. It promotes the research and development of related topics.
