From the viewpoint of software quality measurement , the practical meanings of software metrics to improve software quality is expounded , a methodology of quality measurement is introduced , current models in quality measurement are analyzed and compared . also , a model that suits the environment of practices , named moqem , is proposed , concerning measurement metrics are defined thoroughly , and the model is compared with other relating research activities at home and abroad 本文从软件质量度量的角度,阐述了软件度量刑提高软件质量的实际意义,介绍了质量度量的方法论,分析比较了现行软件质量度量模型,提出了一种适合于度量实践环境的模型( moqem ) ,详细定义了其中的度量指标,并把此模型与国内外其他相关研究活动进行了比较。
The two - stage modeling method takes into account the characteristics of software project risk management and software metrics data , integrates qualitative knowledge and quantitative data . to study the software project iterative process risk ’ s bayesian network model , the definition of cyclic bayesian network is presented , probability convergence property of directed cycle in cyclic bayesian network is proved and probability inference method is put forward 论文在软件项目迭代过程风险的贝叶斯网络模型研究中,定义了有环贝叶斯网络,证明了有环贝叶斯网络中有向环的概率收敛性质,给出了有环贝叶斯网络的概率推理方法。
This dissertation systematically generalizes theory , methods and techniques of software metrics , depicts an inproved software quality metrics model and brings forward a new software metrics tool architecture that based on abstract syntax tree . a software metrics tools named emmetrics is designed and implemented based on the new architecture , so metrics data can be automatically collected , analyzed and exhibited 本文系统归纳了软件度量的理论、方法和技术,改进了已有的软件质量度量模型,提出了一种以抽象语法树为核心的度量工具的体系结构,并且基于该体系结构设计并实现了一个自动化软件度量工具emmetrics ,实现了度量数据的自动采集、分析与展示。
