详细说明： 软件开发成本估计方法 书Software development cost estimation approaches – A survey Barry Boehma, Chris Abts a and Sunita Chulani b a University of Southern California, Los Angeles, CA 90089-0781, USA b IBM Research, 650 Harry Road, San Jose, CA 95120, USA E-mail: sunita@us.ibm.com This paper summarizes several classes of software cost estimation models and techniques: parametric models, expertise-based techniques, learning-oriented techniques, dynamicsbased models, regression-based models, and composite-Bayesian techniques for integrating e xpertise-based and regression-based models. Experience to date indicates that neural-net and dynamics-based techniques are less mature than the other classes of techniques, but that all classes of techniques are challenged by the rapid pace of change in software technology. The primary conclusion is that no single technique is best for all situations, and that a careful comparison of the results of several approaches is most likely to produce realistic estimates. ...展开收缩
