间断需求预测方法综述

间断需求是一种随机需求,需求数据中存在着大量的零值。具有间断需求的物资如备件、贵重设备等对于企业生产运作非常重要,需要精确的预测才能很好地进行管理,但目前研究间断需求预测方法的文献不多,已有的间断需求预测方法适用范围有限,还缺少比较通用的预测方法。本文对现有的间断需求预测方法进行了回顾,分析了当前间断需求预测方法存在的问题,并提出了未来可能的研究方向。

A Review of Intermittent Demand Forecasting Methods

Intermittent demand is a random demand,where there's a large proportion of zero in the demand series.Items with intermittent demand are usually very important for enterprises,and there's great need for accurate demand forecasting for such items.However there are only a few forecasting methods for intermittent demand,which are only suitable for some special situations.This paper gives a review of forecasting methods for intermittent demand.Limitations of current intermittent demand forecasting methods have been summarized and analyzed,and potential direction for future research has been suggested.
