摘　　要：准确的估计是进行有效的项目计划、跟踪和控制的基础.基于模型的成本估计方法是软件成本估计研究的重点,它可分为算法驱动式模型、数据驱动式模型以及复合式模型.依照该分类模式,介绍了典型的软件成本估计方法,并从内部属性及外部评价两个维度共计11个指标对每类方法的假设前提、适用范围、优势及局限性进行深入的分析.最后,对软件成本估计研究的未来发展进行探讨.Accurate estimation is the foundation of effective project planning, tracking and controlling. Model-based methods, in contrast to expert-experience-based methods, are more independent of individual＇s capabilities and more reusable in software development organizations, so they are the focus of research in software cost estimation. They may be classified into algorithm-driven models, data-driven models and composite models. In term of the classification schema, the typical methods are described in detail. Then, their assumptions, application environment, advantages and limitations are analyzed deeply which are viewed from both internal attributes and external evaluation. Finally, the future of software cost estimation research is discussed. The purpose of the paper is to compare the advantages and disadvantages of the representative estimation models and provide support for using the suitable models for software development organization.
