摘要

正确的软件成本估算在软件工程中非常重要。因此，合理评价现有的多种软件成本估算方法，选择最合适的方法具有重要的意义。提出了软件成本估算方法的评估框架。该框架总结了评估方法应该考虑的所有方面。将模糊评价与灰色理论相结合的模糊-灰色综合评价方法应用于软件成本估算方法的评价模型中。它可以充分利用专家评价信息的模糊性和灰色性，使评价更加客观准确。最后，通过实例验证了该评价模型在软件开发项目实践中的实用性和可行性。

Evaluation Model of Software Cost Estimation Methods Based on Fuzzy-Grey Theory

Correct software cost estimation is important in software engineering. So it is significant to reasonably evaluate current lots of software cost estimation methods and subsequently select the most suitable one. The evaluation framework of software cost estimation methods is brought forward. The framework summarizes all aspects that should be considered by estimation methods. Fuzzy-Grey comprehensive evaluation method which combines fuzzy evaluation and grey theory is used in the evaluation model of software cost estimation methods. It can make full use of fuzziness and grayness of evaluation information by experts which makes the evaluation more objective and accurate. Eventually, through an example the evaluation model is proved to be useful and feasible in software development project practice.
