摘　　要：如何做好软件项目预算一直是政府机关、企事业单位进行信息化建设的难题之一。软件成本评估是通过一套流程或模型对软件项目开发的工作量、工期和成本进行评估的行为,可以提高软件预算的精确度,有利于保障软件项目的交付周期,合理安排和调度研发人员。首先,对软件成本评估方法进行分类介绍和对比,分析其优缺点;然后,采用软件项目样本数据,对功能点、用例点、神经网络、类推4种评估方法进行实验分析;最后,指出现有的软件成本评估方法存在的问题和进一步研究的方向。How to do a good job of software project budget has always been one of the difficult problems in the information construction of government agencies,enterprises and institutions.Software cost assessment is a behavior that evalua-tes development effort,time limit and cost of software project through a set of processes or models.It can improve the accuracy of software budget,protect the delivery cycle of software project,and arrange and schedule the research and development programmer reasonably.First of all,the software cost assessment methods were classified and compared,and their advantages and disadvantages were analyzed.Then,the experiment and analysis of four evaluation methods,including function point,use case point,neural network and analogy,were carried out with the sample data of the software project.Finally,the existing problems of the existing software cost assessment methods and the direction of further research were pointed out.
