通用预测支持系统的设计

Design of General Forecasting Support System

基于COM组件的通用预测支持系统包括数据预处理及预测分析。前者为数据库类、电子表格类及文档类等数据设计不同接口。后者含选择模式,组合预测,选择预测指标、时间,模型数量及种类,确定模型比重参数、返回预测结果等步骤。系统在经典预测模型基础上提供单纯预测、组合预测、神经网络预测结果修正3种预测模式。

The common forecasting support system based on COM components includes the data preprocessing part and the forecasting part, The front part designed different circuits for database species, electronic form species and document species, The back part includes choosing modes, combining forecasting, choosing forecasting index, time, modes, and kinds, ensuring mode weighting parameter, returning forecasting results and so on, Based on classical forecasting model, the system provided single forecasting model, combination forecasting model, and neural network modification,
