摘    要:为有效防范软件项目失败风险,必须加强软件项目风险管理的意识和能力。在对软件项目风险管理过程分析的基础上,提出一种基于模糊理论的软件风险评估模型,使用模糊性语言评估风险后果及损失,度量多种风险对某种风险后果的组合影响以及单个风险对整体后果的综合影响,解决专家评估的不确定性问题,增强软件项目风险的预测和应变能力,为有效地降低风险发生概率、提高软件开发成功率提供了一种新途径。

Abstract: Considering that many uncertainties always exist in the development and management process of software project, the awareness and ability of software project risk management must be strengthened to effectively prevent the occurrence of the failure. On the basis of the analysis of the software project risk management process, a model based on fuzzy theory in software project risk assessment was proposed. Using the fuzzy language to assess the consequences and the loss of the risk, the model can measure the combination of impact of a certain risk from a variety of risks and the combined effects of the overall consequences from individual risk, which resolves the uncertainty of expert assessment, enhances the prediction and response capabilities of the software project risk and thus it provides a new way to effectively reduce the risk probability and increases the rate of the success of the software development.
