Sorting and decision-making of multi-attribute intervals are prevalent in engineering systems and socio-economic systems and are an important content of theory and method study of decision-making.The previous study of fluctuation of economic growth is limited to fluctuation of long-term economic growth and its research methods mainly use statistical knowledge.This article combines sorting of multi-attribute intervals with grey incidence theory together,builds multi-attribute intervals of fluctuations based on GDP growth,uses relevant calculation algorithms of grey incidence to monitor the short-term fluctuations quality of national economic growth,and,finally,uses the method in empirical analysis to verify the value and significance of the method in practice. 更多
