Capacity Requirements Planning

Short term capacity planning after the creation or release of production orders.

The following two rules in capacity planning will bring tremendous sanity to the production process.
There is a point in time at which planning activities must end.
Plan your resources in the medium and long term, and manage demand. Plan your resources and sequence in the short term. Then, schedule and manage supply

of materials required for production.Note: Just to note that Medium- to long-term capacity planning,  is conducted via sales and operations planning (S&OP) or LTP.

CRP can be implemented for production orders and also for planned orders from

material requirements planning (MRP) and LTP.

Capacity evaluation ( comparison between available capacities with capacity requirements, with reference to the work center or specific production order.)

Capacity availability check ( available capacity at the requisite work center ) during production order creation or

during its release.

A production scheduler is tasked with scheduling a pool of orders within a certain

time frame.

To do so, the orders first have to be put into a sequence according to

some sort of criteria (maybe heijunka or setup optimization) and then leveled on the

work centers or production line as available hours permit.

Leveling uses the order’s

load and the work center’s availability to figure out at what specific point in time the

order will be placed.
