Combining naive forecasting models as an alternative to using any one model has shown promise for improving forecasting accuracy at reasonable additional cost. This study extends previous combination modeling by selectively including models in combination rather than using all individual models...

The impact of forecasted demand and forecast error, introduced in the Master Production Schedule, upon Material Requirements Planning (MRP) Systems is investigated. A computerized simulation was built to examine several questions. Results indicate that forecasting error, especially the mean...
