SOFTWARE COST ESTIMATION BY FUZZY ANALOGY FOR ISBSG REPOSITORY

Software cost estimation is one of the most important and complex tasks in software project management. As a result, several techniques for estimating development effort have been suggested. Fuzzy Analogy is one of these techniques suggested to estimate project effort when it is described either by linguistic or numerical values. Based on reasoning by analogy and fuzzy logic, this technique uses fuzzy representation of software project attributes by using expert knowledge or clustering techniques. From this work, we evaluate the accuracy of this approach to estimate the software effort using the International Software Benchmarking Standards Group (ISBSG) repository.
