软件项目风险的可拓评价

Extension evaluation for software project risk

将可拓评价应用于软件项目风险评价中。依据物元模型与关联函数理论,分析软件项目风险的各种影响因素,建立可拓评价的物元模型。通过计算该模型综合关联度,得出定量的数值。该数值既表示出软件项目风险的大小,又体现风险转化趋势,有利于制定合理的软件项目风险应对计划。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 dependent function theory, elements that influence software project risk are analyzed then a matter-element model of extension evaluation is built up. A quantitative numerical value evaluating software project risk is acquired by calculating the synthetical dependent degree of this model. It can reveal different levels of software project risk as well as the tendency of risk transform, which lead to rational countermeasures of software project risk. In the end, a scenario presents validation of this method.
