Research Of Economic Systems Analysis Using Optimized Gray Method

The grey system theory which is founded by Professor DengJuLong has been already applied in every sides of social economy. Many researchers have achieved much delectable breakthrough. In allusion to these characteristics including uncertainty of parameter and abroad non-linear, the grey methods and its optimized methods still exist great imaginational space in this applied field .This thesis try to put forward some ideas about the effects of optimized grey forecasting method and grey evaluating method in the economy system analysis.The thesis imports BP neural network to optimize GM(l.l) model based on two characteristic of multiple indexes and small data in the short-term economy system forecasting.This thesis puts forward that it can use gray analytical hierarchy process to solve problem of index power in the evaluation. Based on that, the thesis integrates gray clustering evaluation and gray statistic evaluation to evaluate the salary prompting mechanism of higher-ups in our public companies...
