Demand Forecasting: Evidence-based Methods
In recent decades, much comparative testing has been conducted to determine which forecasting methods are more effective under given conditions. This evidence-based approach leads to conclusions that differ substantially from current practice, . This paper summarizes the primary findings on what to do – and what not to do. When quantitative data are scarce, impose structure by using expert surv...
متن کاملMethods for Intermittent Demand Forecasting
Intermittent demand or ID (also known as sporadic demand) comes about when a product experiences several periods of zero demand. Often in these situations, when demand occurs it is small, and sometimes highly variable in size. ID is often experienced in industries such as aviation, automotive, defence and manufacturing; it also typically occurs with products nearing the end of their life cycle....
متن کاملFindings from Evidence-based Forecasting: Methods for Reducing Forecast Error
Empirical comparisons of reasonable approaches provide evidence on the best forecasting procedures to use under given conditions. Base on this evidence, I summarize the progress made over the past quarter century with respect to methods for reducing forecasting error. Seven well-established methods have been shown to improve accuracy: combining forecasts and Delphi help for all types of data; c...

متن کاملAdaptive Demand-Forecasting Approach based on
In this study, an adaptive demand-forecasting approach adopting the data-mining technique which detects the correlation between the target variable and other related elements, is proposed. With the inclusion of the scheme of the time-series analysis based on the state-space approach, this approach has two characteristic points. One is the state-space which is formed by principal components comp...
