Today’s challenges to sustainability are explored through a complex combination of interdisciplinary topics that explore various interactions between economic, social, and environmental systems further contribute existing uncertainties. Solving complex/dynamic constraints does not demand exclusively technical practical methods, as it is equally important have profound conceptual understanding t...

At same time, set work processes carried out by under specific environmental conditions, using equipment within organizational management structure. purpose this article to identify main factors affect occupational rank terms their effectivene...

The theory instrument of grey relational analysis is grey relational grade between the sequences. The grey relational grade is a measure of the degree of association between two factors, or between two systems. It describes the relative changes among the various factors in the development process of the system. In turn, we can calculate the grey relational grade, compare and judge the grey rela...

Recently, Fuzzy Grey Cognitive Maps (FGCM) has been proposed as a Grey System theory-based FCM extension. Grey systems have become a very effective theory for solving problems within environments with high uncertainty, under discrete small and incomplete data sets. The benefits of FGCMs over conventional FCMs make evident the significance of developing a greyness-based cognitive model such as F...

 Abstract—Grey theory is a truly multidisciplinary to deal with systems that are characterized by few data for which information is insufficient. The grey forecasting model from grey theory was first applied in this paper to predict accurately the green GDP accounting of Taiwan from 2002 to 2010. Concerns about green GDP accounting are regarded as a human welfare indicator of economic progress...

Accurate prediction of the future electricity consumption is crucial for production electricity management. Since the storage of electrical energy is very difficult, reliable and accurate prediction of power consumption is important. Different approaches for this purpose were used. In this paper, Grey model (1,1) based on grey system theory has been used for forecasting results. Annual electric...
