A New Metric for Lumpy and Intermittent Demand Forecasts: Stock-keeping-oriented Prediction Error Costs

  title={A New Metric for Lumpy and Intermittent Demand Forecasts: Stock-keeping-oriented Prediction Error Costs},
  author={Dominik Martin and Phil Spitzer and Niklas K{\"u}hl},
Forecasts of product demand are essential for short- and long-term optimization of logistics and production. Thus, the most accurate prediction possible is desirable. In order to optimally train predictive models, the deviation of the forecast compared to the actual demand needs to be assessed by a proper metric. However, if a metric does not represent the actual prediction error, predictive models are insufficiently optimized and, consequently, will yield inaccurate predictions. The most… Expand
Reframing demand forecasting: a two-fold approach for lumpy and intermittent demand
This research shows that competitive demand forecasts can be obtained through two models: predicting the demand occurrence and estimating the demand size, and proposes a novel evaluation criterion of lumpy and intermittent demand forecasting models' performance. Expand
Demand Forecasting Intermittent and Lumpy Time Series: Comparing Statistical, Machine Learning and Deep Learning Methods
This study compares methods from statistics, machine learning and deep learning by applying a novel metric called Stock-keeping-oriented Prediction Error Costs (SPEC), which overcomes the drawbacks associated with traditional metrics. Expand
Explainable Demand Forecasting: A Data Mining Goldmine
Demand forecasting is a crucial component of demand management. Value is provided to the organization through accurate forecasts and insights into the reasons driving the forecasts to increaseExpand


Evaluation of forecasting error measurements and techniques for intermittent demand
This paper is a part and contribution to develop flexible and robust supply chain forecasting systems under changing market demands. It suggests new tools and models to evaluate forecasting errorExpand
Intermittent demand forecasts with neural networks
Intermittent demand appears when demand events occur only sporadically. Typically such time series have few observations making intermittent demand forecasting challenging. Forecast errors can beExpand
A new metric of absolute percentage error for intermittent demand forecasts
The mean absolute percentage error (MAPE) is one of the most widely used measures of forecast accuracy, due to its advantages of scale-independency and interpretability. However, MAPE has theExpand
The Accuracy of Non‐traditional versus Traditional Methods of Forecasting Lumpy Demand
Forecasting for inventory items with lumpy demand is difficult because of infrequent nonzero demands with high variability. This article developed two methods to forecast lumpy demand: an optimallyExpand
Electricity price forecasting: A review of the state-of-the-art with a look into the future
A variety of methods and ideas have been tried for electricity price forecasting (EPF) over the last 15 years, with varying degrees of success. This review article aims at explaining the complexityExpand
Methods 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, andExpand
Error Measures for Generalizing About Forecasting Methods: Empirical Comparisons
This study evaluated measures for making comparisons of errors across time series. We analyzed 90 annual and 101 quarterly economic time series. We judged error measures on reliability, constructExpand
The accuracy of extrapolation (time series) methods: Results of a forecasting competition
The results of a forecasting competition are presented to provide empirical evidence about differences found to exist among the various extrapolative (time series) methods used in the competition. Expand
Assessing Forecast Accuracy Measures
This paper looks into the issue of evaluating forecast accuracy measures. In the theoretical direction, for comparing two forecasters, only when the errors are stochastically ordered, the ranking ofExpand
