Since it is usually impossible to consider every ̄ne detail associated with the production process while maintaining such a long planning horizon, it is mandatory to aggregate the information being processed. The aggregate production approach is predicated on the existence of an aggregate unit of production, such as the \average" item, or in terms of weight, volume, production time, …

5.1 Aggregate production planning (APP) Aggregate production planning is the process of determining (1) the timing and quantity of production, (2) the level of inventories, (3) the number of workers employed, and (4) the amount of overtime used for up to 12 months ahead. Production and inventories are stated in overall or aggregate quantities, such as number of automobiles …
