| Abstract: | In this paper,a combination of multi-step adaptive forecast system was presented.The system was composed of a number of different parallel adaptive multi-step forecast models,and the final results were determined by a number of forecast models to predict the value of weighted linear combination.This system can be applied to a random process of time-varying dynamic system of multi-step forecast problem.In a forecast of food production trend in a certain province,some effective results were obtained. |
