摘要
软件项目成本估算是软件项目管理的关键步骤,为了使COCOMO适用于中国企业,本文根据特定企业软件历史项目数据对基本COCOMO模型进行校正,比较了经验估算和线性回归两种方法的预测精度。校正后的模型对软件项目开发非常具有实用价值。
Software project cost estimate is the key step to software project management.In order to make COCOMO applicable to Chinese enterprises,in this paper,we calibrated the basic COCOMO model according to the historical software project data of given enterprises,and then compared experience estimate with linear regression about the forecasting accuracy.The model after calibration has practical value to software development.
