Based on existing grey relational degree models, in order to investigate the dynamic similarity of trends between sequences, we propose the grey relational model based on velocity and acceleration which measures the closeness of the rate of change. And then we discuss the nature of the rate of change of gray relational degree. This model can reflect the similarity of the relative change trend of time...
In order to improve prediction accuracy of traffic accidents, an optimization GM (1, 1) power model is put forward based on the characteristics of S-type and a single traffic accident peak. Specifically, an intelligent optimization method is proposed to optimist the parameter α using PSO algorithm and the optimization formula of background value in GM (1, 1) power model is given based on the integral...
Multifunctional agriculture (MFA) has become a widely appLied term. This paper presents an overview of background, theory and tools of MFA. In theory MFA require a special framework in institutional analysis. The IAD and SES framework can make significant contributions in this analysis. Modern techniques, such as remote sensing and GIS, are among the most powerful tools for modeLing, analyzing and...
Mineral resource exploitation has important impact on region economic development, industrialization level and urbanization. Take xinjiang as example, this paper analysis the basic feature of mineral resource exploitation and urbanization, on this basis, dynamic computation model is established to discuss the relativity of mineral resource exploitation, economic development, industrialization level...
This paper studies on the multi-attribute weighing decision model of grey target based on theories of decision-making analysis. Concerning of Savage decision criteria under the circumstance of uncertain decision, grey interval number series have been put forward to extend definition of real number series as well as a ranking method has been given according to the distance from Grey target. In this...
