Aggregate production functions are reduced-form relationships that emerge endogenously from input–output interactions between heterogeneous producers and factors in general equilibrium. We provide a general methodology for analyzing such aggregate production functions by deriving their first- and second-order properties. Our …

Definition. Aggregate planning is a way to plan the production of all products for a company over a period of time. It starts by listing all the important requirements for uninterrupted production. The usual planning horizon ranges from three to twelve months. The word 'aggregate' comes from the Latin word 'aggregāre.'.

Artificial aggregates (AAs) are man-made construction material, and the properties greatly depend on its manufacturing process (e.g. granulation and hardening) and the raw materials (usually different source of wastes) used. This paper reviews the granulation process and suitable raw materials for each hardening method.
