Prediction on Stress during Bone Fracture Healing based on Equal-dimension and New-information odel of GM(1,1)

摘要

Research results show that stress is one of the main factors affecting bone fracture healing which is a complex process,. In order to guarantee the speed and quality of bone fracture healing as well as its stress changing tendency, this paper introduces an equal-dimension and new-information model of GM(1,1) to forecast the stress on fracture of the following day according to the stress data which has already been measured. In this paper, establishment method of the equal-dimension and new-information model of GM(l.I) and the practical example of prediction on fracture face stress are given. The result of prediction calculation shows that the stress prediction method proposed in this paper is feasible. It can obtain a better prediction precision, and the result can meet the application request.
