The theory underlying the aggregate production function is as follows. In each period, there is a set of plant technologies B. A plant technology b ∈ B is a triplet that gives the plant's output y b and its capital and labor inputs, k b and n b. A plan { λ b } specifies the measure of every type of plant operated.

Aggregate production functions not well founded in theory. Disagreement on curiosity vs. deep problem. Keeps being used for empirics. After short detour of "general equilibrium" approach (Bliss, Hahn), RBC revolution leads to quasi-universal adoption of aggregate production functions and neglect of controversies.
Aggregate production planning typically is applied to a 3- to 18-month period. Aggregate planning covers all production activities at a facility (or for large enterprises, across several facilities), not just individual production runs or manufacturing individual products. Because of this, aggregate production planning helps manufacturers ...
The aggregate production plan helps supply chains reduce costs, such as the cost of paying a stagnant labour force, the cost of holding inventories, and the cost of missed opportunities. Each aggregate strategy mentioned earlier holds some advantages and disadvantages in this regard, leaving the supply chain to decide what it is ok with.
