A forecast netting and consumption model for advanced planning and scheduling

This paper features an advanced planning system (APS) in which the forecasts and customer demands are balanced to arrive at the netted forecast for the production system to produce purchase orders and production orders. The forecast process to collaborate the demand and the forecast is rarely considered in the planning and scheduling models. In this paper, a new decision support process for netting forecast is presented, which includes two processes to prepare the netted forecast for the weekly and daily production planning, respectively. The weekly forecast netting process does the netting for the weekly demand, and the daily forecast consumption process handles the daily demand. The proposed approaches are being applied in a practical application of APS system, which is implemented in Alcatel Shanghai Bell.
