区间型关联函数在软件项目风险评估中的应用

Application of interval elementary dependent function in software project risk evaluation

将可拓评估应用于软件项目风险评估中。该方法依据物元模型与区间型关联函数理论,分析了软件项目风险评估准则,建立风险评估的物元模型。通过计算该模型的综合关联度,得出定量的数值。该数值既表示出风险量的大小,又体现风险转化趋势,从而可作为风险转化指标,以确定何时启动风险应对计划。最后通过案例验证该方法的有效性。

Extension evaluation is utilized in this paper to assess software project risk.According to matter-element model and interval elementary dependent function theory,rules that assess software project risk are analyzed then matter-element models of risk evaluation are built up.The quantitative numerical values evaluating software project risk are acquired by calculating the synthetically dependent degree of the models.They can reveal different levels of software project risk as well as the tendency of risk transform.Thus they can be selected as risk transform index,which confirm to whether startup countermeasures of software project risk.In the end,a scenario presents validation of this method.
