Multi-granularity Object-oriented Software Estimation Model
Chen Li · 2009
Software cost estimation is not only a significant researching aspect of software engineering,but also a good means to control software cost and schedule.Object-Oriented(OO),as a leading metric of software development,now its estimation is a hotspot of software cost estimation.Until now,most OO estimation methods are variations of FP method.These methods are lacking in uniform estimation system and have a comparative relative error.Aiming at the above problems,this paper presented a multi-granularity estimation model and gave a minute description according to classical metrics,then analyzed the relationship between the software size and effort by Ordinary Least-Squares(OLS)regression analysis.Finally this paper evaluated the result of experience.
