摘要: 用传统的经验函数估算软件成本有很多局限性,采用基于范例库推理的估算方法可以很好地弥补其中的问题。讨论了软件成本估算和基于CBR推理研究的特点,从总体上阐述了COSCBR系统结构,描述了系统重要的研究方面:影响软件成本因素;层次推理;COSCRB系统的范例表示方法;相似度的基本计算算法。

Abstract: Software cost estimate with the traditional experience function has the shortcoming, and applying CBR estimate method can make up these problems. This paper describes the research on software cost estimate and the CBR characteristic, introduces the COSCBR system architecture. The essential aspects are presented: the structure of the software cost factors; the hierarchy reasoning process; the COSCRB case expression; and the calculating similarity arithmetic.

Key words: Case-based reasoning(CBR), Software cost, Similarity, Hierarchy reasoning
