What is Loading in Production Planning and Control?
In planning production, shop orders have to be converted into work load on individual work machines or groups of machines.

Importance of loading:

The production manager must know the loading on each equipment/machine in order to determine whether capacity utilization is full or otherwise. He should also identify overloads and under-loads on each machine to assist production planning to balance the load.

Manual system:

Manual systems generally used to load operations against actual capacity by creating a bar chart on a load board. The design of the loading board is made to suit the specific needs of the system.

The board comprises of a list of resources (machines) on the left, a time scale across the top and bars of different lengths against each resource to indicate the extent of loading.
