...Wenjie Dong; Sifeng Liu; Zhigeng Fang Purpose The purpose of this paper is to study the modelling mechanisms of several grey incidence analysis models with great influence, including Deng’s grey incidence model, absolute degree of grey incidence model, slope degree of incidence model, similitude...

... and quality level in practical application, all of these models cease to work. In this paper, we first discuss the modelling mechanism of several original cost control models, and then propose a new method for forecasting quality costs based on a discrete grey model (DGM). In order to eliminate...

... demonstrate the orientation of grey system modeling. Practical implications Theoretical framework is very important for developing a new theory. This paper clarified grey information and grey system-based modeling mechanism. It is very useful to understand and explain the systematic framework of GST...
