摘　　要：为了对当前多种软件成本估算方法进行合理评价,从而选择最合适的方法,做出最精确的软件成本估算.采用基于模糊理论的综合评价方法,按照提出的软件成本估算方法的评价体系,对估算方法进行评价.该评价体系概括了估算方法应考虑的各方面,针对评价体系中的评价指标大多只能定性描述,采用模糊综合评价方法能充分考虑评价时的主观性与模糊性,因此评价结果更客观.通过实例研究,证明了该模糊综合评价方法可以有效地对估算方法进行评价,对软件开发项目实践有参考价值.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.
