A fuzzy integrated evaluation method for software cost estimation

In order to select a suitable method to achieve the most accurate software cost estimation,an integrated evaluation method based on fuzzy theory is used to evaluate current software cost estimation methods according to the evaluation framework brought forward.The framework summarizes all aspects that should be considered by estimation methods.Aimed at the problem that most evaluation indexes in the evaluation system only can be described qualitatively,the fuzzy integrated evaluation method can consider the subjectivity and fuzziness sufficiently in evaluation,therefore the obtained evaluation result is more objective.An instance research proves that the fuzzy integrated evaluation method is useful for evaluating estimation methods and can provide a reference to software development project.
