摘　　要：针对软件可靠性度量研究中的一些问题,提出了以缺陷度量为软件可靠性度量的一种方法。首先将缺陷度量方法按照软件度量的一般方法进行研究和探讨;其次,以正交缺陷为基础,提出了定量的缺陷统计方法,这种方法能够更好地描述缺陷的性质,对相关信息可进行分类统计、分析,为过程改进提供依据;最后,提出了一些定性的缺陷分析方法,可充分挖掘缺陷的潜在信息。按照软件度量的步骤,通过定性和定量相结合的方法,可以很好地度量软件可靠性,并实时提高软件可靠性。To metric software reliability,a new method based on defect is presented.According to the common process of software metric,a research on software reliability metric which is based on the real defect is made firstly.Then the quantitative defect statistic method is applied which is based on ODC.This method can describe the information of defect well and can be used for process improvement.At last,the qualitative method of defect analysis is showed,which can dredge up underlying information.According to the common process of software metric and combine of quantitative and qualitative method,the software reliability can well metric,and the software reliability can be improved real time.
