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. Labor—the number of hours that are worked in the entire economy.

Changes in the aggregate production function. The factors that contribute to aggregate production include the labor force, capital, and technology. When these factors increase, they can lead to an increase in production. Additionally, productivity, or …

Aggregates are a broad category of construction materials. In terms of tonnage and number of quarries and mines world-wide, aggregates represent the largest mineral production tonnage excluding energy minerals. Range of grain/rock sizes. Concrete sand and asphalt sand have a grain size of 4.75 mm (0.18 inch) to 0.075mm (0.003 inch).

Aggregate quality is of great importance, and in this context it is essential to understand how various process parameters influence the product quality characteristics. Thus, there is a need for aggregate producers to improve their process knowledge. Research has led to an improved understanding of how different process parameters affect the outcomes of …

This article presents a mathematical model for production planning in a SC under demand uncertainty and solves it by a fuzzy multi-objective optimisation method. This model is formulated as multi-objective mixed-integer non-linear programming with conflicting objective functions.

Aggregate is the main component of concrete which covers more than two-third parts by volume. Hence cost of the concrete is influenced by its aggregate. The strength of hardened concrete depends upon quality of its ingredients. Cement is the costliest ingredient in concrete and by using quality aggregate it can be economized.

Aggregate production planning (APP) involves the simultaneous determination of company's production, inventory and employment levels over a finite time horizon. Its objective is to minimize the total relevant costs while meeting non-constant, time varying demand, assuming fixed sales and production capacity. Despite numerous and …

An aggregate production function (PF) relates total output to total employment, assuming all other factors of production and technology are fixed. It shows that increases in employment lead to increases in output but at a decreasing rate. It is easy to picture the problem of diminishing marginal returns in the context of a single firm.

The flowchart of the complete recycling process is presented in Fig. 2.1.

Definition of Aggregate Production Function. An aggregate production function is an economic model that represents the relationship between the total output of a nation and the amounts of various inputs used to produce that output. It is a theoretical concept that describes how, in the economy as a whole, total gross domestic product …

Aggregation concerns the conditions under which several variables can be treated as one, or macro-relationships derived from micro-relationships. This problem is especially important in production, where, without proper aggregation, one cannot interpret the properties of the aggregate production function. The conditions under which …
