摘　　要：软件规模估算是软件成本度量中最重要的环节。针对当前主流功能点分析方法中组件复杂度等级确定方法中存在的不连续问题,提出了一种基于模糊综合评判功能点分析法,有效解决了复杂度划分不连续、不准确等问题。应用模糊综合评判法,以记录元素数据类型和数据元素数据类型作为影响组件复杂度的因素集,以复杂度等级作为评语集,选取适合的隶属度函数进行多指标评价并生成模糊矩阵,加权进行线性变换后算得转换功能点数。研究结果表明,这种方法可使功能点估算准确率进一步提高,所得到的功能点估算结果更加贴近软件工程实际。Software size estimation is the most important part of software cost measurement.Inorder to solve the problem with the complexity level in mainstream function point analysis method,a function point analysis method based on fuzzy comprehensive evaluation method is proposed,the method effectively solves the discontinuous and inaccurate division of complexity and other issues.The RET(recorded element type)and DET(data element type)are used as the factor set that affects the complexity of the component,and the complexity level is used as the comment set.Anappropriate membership function is selected for multi-index evaluation,and the fuzzy matrix is generated.After linear transformation,the exact function points are calculated.The research results show that this method can further improve the accuracy of function point estimation,and the obtained function point estimation results are closer to the actual software engineering.
