(PPT) Aggregate Planning
Definition The term Aggregate Planning is defined as, “An operational activity which does an aggregate plan for the production process, in advance of 2 to 18 month, to give an idea to management as to what quantity of materials and other resources are to be procured and when, so that the total cost of operations of the organization is kept to minimum over that period”.

Ideally therefore, aggregates should be stockpiled on a concrete slab. If this is not done, the layer of aggregates in contact with the soil should not be used for production. Aggregates must not be stockpiled under trees. Partitions should be erected between different types of aggregate. Stockpiles should be on a slight slope so that rainwater
