基于MATLAB/GUI灰色预测系统开发及应用

针对GUI设计开发系统在经济领域中的应用问题,本文以灰色预测模型为理论基础,通过GUI控件的布局设计及回调函数程序的编写,开发了基于Matlab GUI的灰色预测系统,实现了GM(1,1)模型的参数估计、检验、数据拟合及预测,解决了模型建立和求解过程实现复杂的问题。同时,选取2003—2010年的国内生产总值作为测试数据对系统进行测试。测试结果表明,灰色预测系统界面友好,操作简单,准确实现GM(1,1)模型,并得到了模型的相关结果。该研究提高了灰色预测模型的利用度。

Development and Application of the Grey Forecasting System Based on MATLAB/GUI

For the application of using GUI developing system in the economic field,grey forecasting sys- tem, based on the grey system theory, was developed by MATLAB GUI through the design of control unit and programming of callback function. The system can get the results of GM（1,1） model, including pa- rameter estimation test, fitting and data forecasting. It solves complex issues including modeling and sol- ving. Simultaneously, it was tested by data of Gross Domestic Product from 2003 to 2010. The result of test shows that grey forecasting system is easy to operate. It can realize GM（1,1） model and relevant re- sults accurately. This study improves the utilization of gray prediction model.
