【摘要】 由于预测对象的复杂性和不确定性,原始数据往往用区间数形式给出,同时预测值也是利用各个单项预测模型以区间数形式给出。本文针对区间时间序列,提出了区间中心误差、左、右端点误差等概念,并构建了基于最大误差绝对值最小化的多目标区间型组合预测模型,并讨论了模型的求解。实例分析结果表明本文所建立的模型的实用性和有效性。更多还原

【Abstract】 Due to complexity and uncertainty of forecasting problems,the raw data are provided in the form of interval numbers.In the meantime,the forecasting values are also given in the form of interval numbers by single forecasting models.We present some concepts of errors for the interval time series, such as center errors,absolute left and right limit errors etc.We construct an interval combination forecasting model of multi-objective programming based on minimizing maximum absolute errors,and discuss the solution to the model.Finally,an example is examined to show the validity and practicality of this proposed model.更多还原
