A Fuzzy Model for Function Point Analysis to Development and Enhancement Project Assessments

Function Point Analysis (FPA) is among the most commonly used techniques to estimate the size of software system projects or software systems. During the point counting process that represents the dimension of a project or an application, each function is classified according to its relative functional complexity. Various studies already propose to extend FPA, mainly aimed at achieving greater precision in the point assessment of systems of greater algorithmic complexity. This work proposes the use of concepts and properties from fuzzy set theory to extend FPA to FFPA (Fuzzy Function Point Analysis). Fuzzy theory seeks to build a formal quantitative structure capable of emulating the imprecision of human knowledge. With the function points generated by FFPA, derived values such as costs and terms of development can be more precisely determined.
