The procedures used to meet present quality standards result in a loss of up to 50 percent of the good seed even though many special machines and techniques are used for seed cleaning and handling. Attempts are being made to reduce seed losses by developing equipment and methods
Tests with this equipment have produced data that show strong correlations between the wavelet-based particle descriptors and visual perceptions of the aggregate morphological properties.
Aggregate production planning also exploits plant and equipment utilization and profits. The efficiency of aggregate production planning is a production plan that indicates how many workers are needed in each period, the amount and type of production such as regular, overtime, subcontracting, etc., and the units to be produced, stored, and ...
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 ...
