Food is an essential ingredient needed by humans. In addition to being consumed, it can also be a valuable commodity for economic purposes through productivity of food crops. Therefore, this study aims model the forecasting maize in Indonesia using Production and Operations Management-Quantitative Method (POM-QM) software.

Oil monitoring for wind turbine gearboxes can reflect wear and lubrication conditions, better identify pits on the tooth surface, fatigue wear, other early faults. However, oil with one or several single predicting models brings inaccuracy due to intrinsic merits demerits of models. In this work, fault pre-warning were studied based inspection data three turbines that have been working continuo...

The paper deals with extensions of exponential smoothing type methods for univariate time series with irregular observations. An alternative method to Wright’s modification of simple exponential smoothing based on the corresponding ARIMA process is suggested. Exponential smoothing of order m for irregular data is derived. A similar method using a DLS (discounted least squares) estimation of pol...

This paper presents research conducted on the case of food retailer in Serbia in order to answer at which level are the forecasting techniques applicable to such companies, at given supply chain model and in given environment. We will validate the usability of TrendSeasonality-Corrected Exponential Smoothing (Winter’s Model) as a model that can improve inventory management in such case.
