扩展的用例点估算方法

Extended Use Case Point Estimation Method

通过分析用例点估算技术的不足之处,提出了两个扩展方法:一是使用模糊集理论扩展用例复杂度权重因子表,使权重因子能够更准确地反应事务数目的变化,从而使估算的结果更准确、可信;二是采用分解的方法使用例点方法能够实现对单个用例的估算,为项目计划提供必要的数据支持。扩展方法简明实用、灵活性强,易于软件组织实施和推广。

Analyses the shortcoming of the use case point （UCP） estimation method. Then two extensions of UCP was proposed, one extended use case complexity weight table uses the theory of fuzzy set, which makes weight factor he able to reflect the change of numher of transaction more precisely; the other extension make UCP can be used to estimate the size of single use case by decomposition which can provide essential data support to project plan. The extended method is concise, practicable, flexible and easy to popularize.
