Software size estimation is the key of entire software program project,and the exact estimation immediately relates to the success of the project.Traditional Function Point Analysis(FPA) has the deficiency of complexity grade analysis.In order to deal with the problem,an improved method for computing complexity weight is proposed.The method analyzes the complexity weight of function component by the fuzzy theory.Firstly,fuzzy logic system for analyzing weight is established.The inputs of fuzzy system are Data Element Types(DET) and Record Element Types(RET),and the output is the component's complexity weight.Then,according to the relationship between complexity and function point,the fuzzy rules are set.By using these fuzzy rules,the complexity weight can be computed.The results of research show that the method can eliminate discontinuity among the different grades and enhance the accuracy of function point estimation.
