aggregate planning decomposition

California State University, Sacramento | Sacramento State

Aggregate planning is usually performed in broad and general terms at the . product line (group) level. A common unit of measurement (e.g., weight, volume, labor hours) is used to describe the output levels in a production plan. Aggregate planning is quite complicated with variable demand and/or supply. The
