摘　　要：软件成本估算的准确性对软件开发管理至关重要。该文在对软件项目成本估算方法进行系统介绍和分析的基础上,讨论了把软件维护阶段考虑在其中并把开发阶段分阶段估算的必要性,据此提出了一种阶段分析估算的方法,并研究了阶段分析法与COCOMO模型相结合来进行成本估算的可行性。采用阶段分析法,有利于项目的合理跟踪和控制;与COCOMO模型相结合,则可有效避免单方法计算的偏差问题,有利于提高估算的准确性。The accuracy of software cost estimation is essential for software development management.By analysing and introducing the estimation methods of software project cost systematically,the paper discussed the necessary of considering the software maintenance phase and estimating the cost by separate the development into several small stages,and then proposed a estimation method of stages divided,finally discussed the feasibility of estimating cost by combining the method of stages divided with the COCOMO model.The use of stages divided method contributes to the track and control a project reasonably;the combining with the COCOMO model can avoid the bias problem due to a single method effectively and can help to improve the accuracy of estimation.
