Aggregate Planning: Tips & Strategies

AP typically addresses 3-to-18-month sales predictions, inventory management, and production levels. Production planning includes commodities and services. Aggregate planning determines the facilities, manpower, raw materials, and inventories needed to meet supply deadlines and reduce costs. This applies to multiple production lines and products.

Aggregation (Production)

Consider a single . Suppose that we wish to describe behaviour in terms of aggregate commodities such as 'food' or 'clothing'. By Leontief's Theorem, a food aggregate exists if and only if the marginal rate of substitution between any two kinds of food is independent of consumption of any non-food commodity.

16.15 The Aggregate Production Function

Specific Forms for the Production Function. We can write the production function in mathematical form. We use Y to represent real GDP, K to represent the physical capital stock, L to represent labor, H to represent human capital, and A to represent technology (including natural resources). If we want to speak about production completely generally, then we can write Y = F(K,L,H,A).
