Estimating software cost based on grey theory
Jianwen Wang · 2010
It is difficult to use the current methods to make predictions.A novel method based on grey theory is proposed.The design thought,key technique and experiment are given.This method gets the effort sequence changing feature-changing from the completed stage effort sequences,and gets thechanging ratio thresholdfrom historical projects by machine learning methods,then uses grey models to make predictions.The experimental results show that,compared with linear regression method,the prediction accuracy of the proposed method has been improved by 10%～50%.
