| Abstract: | Applying CBR estimate method can make up for the shortcomings of software cost estimate with the traditional experience function. This paper describes the research on software cost estimate and the CBR characteristic, and introduces the CBR system architecture of the software cost estimate of the equip- ment. The essential aspects presented are the software cost factors;the CRB case expression;the calculating similarity arithmetic and the case revise. This method is verfied with the true example. |
