Estimation of Software Effort with Market Approach Based on Analogy Evaluation

With rapid development of the software industry, the evaluation of computer software has been paid more attention. The specific steps of analogy estimation and calculation method of similarity measurement are. proposed with evaluation theories and practical characteristics of software, which are based on evaluation models of software value analogical estimation and their application. The results show that the proposed calculation method has significant improvement in maneuverability of evaluation practice and objectivity of evaluation results because it overcomes the defects that academic papers put emphasis on theories. Therefore, this method lays the foundation of widely application of market approach in software evaluation.
