This article concerns the subject of demand forecasting and stocks status planning in online shops. One described the … analysis of surveys results. They were conducted in 616 Polish online shops. The investigation concerns methods of demand …

We study the impact on inventory of an unexpected, non-linear, time-dependent demand and present the exact solutions … stability at infinity, from which we derive expressions for the estimated demand and the target work in progress when the demand … is time-dependent. The resulting inventory equation is solved in terms of the Lambert modes with all of the demand non …

Adaptations of simple exponential smoothing are presented that aim to unify the task of forecasting demand for both … approximations for the so-called lead-time demand distribution, something required for inventory control calculations. The proposed … methods are illustrated and their performance compared on real demand data for car parts. …

finding the prediction distribution of aggregate lead- time demand for use in inventory control calculations is considered. It …
