Research on a Software Cost Estimation Tool Based on COCOMO

The cost management is a main content of the software project management while the software cost estimation stands as the major part of the project cost management.

Considering the difficulty of software cost estimation, the authors introduce the single stage algorithm based on regression model and summarize the linear and nonlinear motive multi-object and multi-stage algorithm for software cost estimation.

It is very important to evaluate software cost estimation method reasonably and subsequently select the most suitable one from current lots of software cost estimation methods.

In order to select a suitable method to achieve the most accurate software cost estimation,an integrated evaluation method based on fuzzy theory is used to evaluate current software cost estimation methods according to the evaluation framework brought forward.

Hybrid method for software cost estimation and risk assessment;

Research on the software cost estimation based on the robust regression algorithm;

Model-based methods, in contrast to expert-experience-based methods, are more independent of individual s capabilities and more reusable in software development organizations, so they are the focus of research in software cost estimation.

Software estimation has been the focuse of many research.

Analogy is the most common and comprehensible method among software estimation methods.
