摘要
针对军用型号项目软件研制过程中普遍存在的软件复用行为,提出了一种复用成本度量方法,对传统的COCOMO2.0成本度量模型进行了改进,采用改进的功能点法估计软件实际规模,适当调整模型中的评估项,增加了度量系统复用的成本驱动因子及系统通用特性统计项(GSC),建立了相应的量化评估及DI分级表,形成了军用型号项目软件进度、成本估计模型,使用改进的度量模型对某军用型号项目进行了成本度量,验证了方法的有效性。
Owing to the widely application of the software reuse technology during the process of military serial project development, a cost model is proposed for software developing with reuse. In this model, the COCOMO2.0 is improved by means of estimating the actual workload using the function point method, and it properly adjusts the model criteria,such as the creation of the reuse driving scaling factors and General System Characteristic（GSC）, and also the corresponding degree of influence table. The improved measurement model and the traditional COCOMO2.0 model are utilized respectively to measure the cost of a software project which is part of a military serial product. By comparing the results with the actual schedule and cost of the project, the effectiveness of the improved model is proved.
