CRP (capacity requirements planning) - ✔determines if sufficient resources are available

FMS (Flexible Manufacturing System) - ✔a type of system that combines the flexibility of intermittent operations with efficiency of continuous operations.

MRP (Material Requirements Planning) - ✔A set of techniques that uses bill of material data, inventory data, and the master production schedule to calculate requirements for materials. It makes recommendations to release replenishment orders for material.

Further, because it is time-phased, it makes recommendations to reschedule open orders when due dates and need dates are not in phase. Time-phased MRP begins with the items listed on the MPS and determines (1) the quantity of all components and materials required to fabricate those items and (2) the date that the components and material are required. Time-phased MRP is accomplished by exploding the bill of material, adjusting for inventory quantities on hand or on order, and offsetting the net requirements by the appropriate lead times.

CRP - Capacity Requirements Planning - ✔available capacity is compared to calculated workloads of relevant items. it provides the ability to compare available production capabilities to the planned workload.
