摘要
证据理论是一种经典的处理不确定性信息和解决信息不完整的方法,软件属性和质量因子大都具有模糊性,很多因子不能用确定的数值表示。基于ISO/IEC9126质量模型中给出的27个软件子特性,利用证据理论及其合成规则计算了软件功能可信度,并给出了实例说明该方法的有效性。最后,总结了该方法的不足。
Evidence theory is a classic way to deal with uncertain and incomplete information. Software attributes and quality fac-tors are fuzzy so that many of them can’t be expressed by precise figures.Software function trustworthiness and quality is evaluat-ed quantitatively using evidence theory based ISO/IEC 9126.An example is given to demonstrate validity of this means.
