A "Production System" is a system whose function is to transform an input into a desired output by means of a process (the production process) and of resources. The definition of a production system is thus based on four main elements: the input, the resources, the production process and the output.

The aggregate production function describes how total real gross domestic product (real GDP) in an economy depends on available inputs. Aggregate output (real GDP) depends on the following: Physical capital—machines, production facilities, and so forth that are used in production. Human capital—skills and education embodied in the workforce ...

Aggregate production functions are reduced-form relationships that emerge en-dogenously 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.

Aggregate Production Planning (Sales and Operations Planning (S&OP)) Sales and Operations Planning is: • prepared for product families (i.e. products with similar labor, material or processing requirements); e.g., passenger tires. • in aggregate terms such as total units (e.g. Camry [s), standard labor hours or dollars.
