软件项目开发工作量估算研究

摘要

Accurate workload estimate is an essential method of guaranteeing software development. Function point analysis is used to estimate software scale. After finishing the software structure disassemble and the project workload disassemble, we use COCOMO Ⅱ 2000 model to estimate software initialization function points and adjustment function points, also transform function point into KSLOC.Thus a basic method is provided for software development company to process workload estimate. Finishing project workload estimate also is the precondition of software cest estimation.%准确的工作量估算是保证软件开发正常进行的必要手段.文中采用功能点估算法,通过对软件结构分解和工作结构的分解,利用COCOMO Ⅱ 2000模型估算初始功能点数、估算调整后的功能点数,最后将功能点转化为源代码行,为软件开发企业提供了进行软件项目开发工作量估算的基本方法.工作量估算是软件开发企业完成成本估算的前提.
