Improved Grey-Topology Algorithm for Forecasting

Scientific forecast is of great importance to the economic phenomenon research and economic decision-making. Therefore, the research about economic forecast theory and method is always a hot topic. This paper proposed an algorithm combined with the grey model, least square method and topology model, which can be a new advanced algorithm for forecasting. Using this new algorithm, the paper forecasts the tendency of average energy consumption per person of our country and then come to the conclusion that the new algorithm is more accurate. It proves that the new algorithm is a good one and can be used by authorities to make strategy decision for economy.
