基于改进用例点软件规模估算方法研究

Research on the size of software evaluation based on improved use case point estimation method

将常用的用例点软件规模估算方法进行研究,分析其在实际应用过程中出现的不足之处。在原有用例点软件规模估算方法基础上,考虑不同角色与系统交互信息量大小和不同用例之间系统内部的复杂度情况,提出一种改进的用例点软件规模估算方法。通过实际案例验证,结果表明采用改进的用例点软件规模估算方法得到的估算结果值的偏差率、标准差和变异系数均显著优于常用的用例点估算方法。

The commonly used use case point software size estimation method is used to analyze the shortcomings in the practical application.On the basis of the previous use case point scale estimation method,considering the amount of information between different actor and system,as well as the complexity within the system between different use cases,an improved method of use case point scale is proposed.Finally,through practical cases,and it shows that the deviation rate,standard deviation and coefficient variation from the result obtained by improved estimated method is significantly better than the common one’s.
