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.

Internal policies and regulations with respect to alternatives. Aggregate planning methods help organizations communicate goals and ways to achieve them. The only way to reach these objectives is by using resources efficiently. Aggregate planning is typically done 12 months into the future.
