Research on Software Cost Evaluation Model Based on Case-based Reasoning

Applying Case-based Reasoning estimation method is an advanced technology in AI and ES, and it can make up for the shortcomings of software cost estimate with the traditional experience function. This paper describes the process of software cost estimate based on case-based reasoning. Distilling method of the cost driver factors based on gray relational grade analysis, similarity metrics is defined as Euclidian distance. The method is verified with the true example from the COCOMO’81 historical dataset.
