Abstract

Software Cost Estimation (SCE) is a hot area of research in the field of development of software projects. Precise estimation of the efforts put on development of software projects, in term of person-month (PM) and development time, is an essential earlier startup of projects. There are several software cost estimation techniques, such as algorithmic and non-algorithmic. This study presents a comparison among two algorithmic methods, namely Baily-Based model and Constructive Cost Models (COCOMO-II). The simulation is conducted on Turkish and Nasa datasets. From the excremental results, it is evident that COCOMO-II is better than the Bailey-Basili in term of Mean Magnitude of Relative Error (MMRE)

软件成本估算——COCOMO-II模型与Bailey-Basili模型的比较研究
软件成本估算(SCE)是软件项目开发领域的研究热点。以人月(PM)和开发时间为单位,对软件项目开发的工作量进行精确估计,是项目早期启动的必要条件。有几种软件成本估算技术,如算法和非算法。本研究比较了两种算法方法,即基于贝利的模型和建设性成本模型(COCOMO-II)。模拟是在土耳其和Nasa的数据集上进行的。结果表明,COCOMO-II方法在相对误差均值(MMRE)方面优于Bailey-Basili方法。
