航天型号软件代码质量度量评估实现

Quality measurement evaluation implement in aerospace software

结合和完善Logiscope和McCabe两种软件度量体系,根据航天型号软件的具体特点,选取出依据软件程序代码的可量化测量度量元,同时修改并增加了3个新定义的度量元,并通过测试不同型号的软件确定出模型参数,建立质量度量评估模型。本研究成果有助于航天型号软件的量化评价,为质量管理人员了解软件质量水平、软件设计师改进软件程序质量,提供量化的客观依据。

According to the characteristics and requirements of the software engineering in aerospace, the paper offers the metrics for the quantifieational measurement of software source codes, these metrics are based on the Logiseope and McCabe measurement system. There are three newly defined metrics especially for the de- mand of the current software in aerospace. To evaluate the metrics, the paper gives a general rating model and its calculating method of model parameters. To determine the parameters of each metric rating model, the statistical data of metrics are analyzed through testing different software samples, and the parameters of the metric rating model result from the analysis. The paper indicates the model can efficiently assess the software in aerospace, which will help quality controllers and software designers to assess software quality objectively and improve it.
