灰色预测系统GM(1,1)模型及其Matlab实现

GM(1,1) Model and Matlab Application of Gray Prediction System

灰色模型有严格的理论基础,最大的优点是实用,用灰色模型预测的结果比较稳定,不仅适用于大数据量的预测。目前,灰色模型GM(1,1)已广泛应用于工程技术、社会、经济、农业、生态、环境等各种系统的预测中。文章根据所建立的GM(1,1)模型以及模型分析,来预测未来安阳市旱灾发生年份,以期积极主动地采取措施进行防旱抗旱工作提供科学依据。

Gray model owns strict theatrical basis,the biggest advantage is practical,the conclusions predicted by gray model is more stable,not only suitable for the current prediction of mass data quantities,but also applies widely in project technology,society,economy,agriculture,ecology and environment etc,. According to GM（ 1,1） model established and model analysis,this paper predicts the years of disasters will happen in Anyang City in the future,supply scientific accordance to adopt actively safe measures to control the draught disasters.
