Lead-time demand forecasting constitutes the backbone of inventory control. Although there has been a considerable amount research on mean lead-time demand, less centered around variance, especially in case stochastic lead-times. This represents an important gap literature, given that safety stock calculations rely explicitly variance (or equivalently forecast error for unbiased estimators). We...

The literature on inventory control discusses many methods to establish the level of decision parameters-like reorder levels or safety factors-, necessary to attain a prescribed service level. In general, however, these methods are not easy applicable: they often use time-consuming iterations, requiring specific software. In particular, large-scale application on huge numbers of stock keeping i...

This paper concerns modelling and policy synthesis for regulation of multiclass queueing networks. A 2-parameter network model is introduced to allow independent modelling of variability and mean processing-rates, while maintaining simplicity of the model. Policy synthesis is based on consideration of more tractable workload models, and then translating a policy from this abstraction to the dis...

The purpose of this research is to design a subsidized fertilizer information system equipped with prediction safety stock method. This study uses the waterfall methodology stages Analysis, Design, Coding, and Testing, as well method for prediction. By testing using black-box modeling Unified Modelling Language (UML) Business Process Model Notation (BPMN). results are prototype data collection ...
