CPIM CPIM Master Planning and MRP Questions and Answers 2

Question 1

What is the Master Production Schedule (MPS) responsible for?

Accepted Answer

Specifying what end items to produce, in what quantities, and when

Answer

The MPS translates the sales and operations plan into specific production quantities and timing for end items or critical subassemblies.

Question 2

Which concept in master planning refers to the policy of not changing the MPS within a defined short-term window?

Accepted Answer

Time fencing

Answer

Time fencing establishes rules about how freely the MPS can be changed within different planning horizons to balance responsiveness and stability.

Question 3

What is 'available-to-promise' (ATP) in a master planning context?

Accepted Answer

The uncommitted portion of planned production that can be promised to new customer orders

Answer

ATP logic calculates how much of the planned production is not yet allocated to existing orders and is therefore available for new commitments.

Question 4

In master planning, what does a 'rough-cut capacity plan' (RCCP) validate?

Accepted Answer

That the MPS is feasible against key resource constraints before running MRP

Answer

RCCP checks the MPS against critical resources (key machines, labor, supplier capacity) to identify major feasibility issues early.

Question 5

What is the 'planning horizon' in the context of the MPS?

Accepted Answer

The total time span covered by the master schedule, which must be at least as long as the cumulative lead time

Answer

The planning horizon must extend at least as far as the cumulative lead time to ensure all lower-level components can be planned in time.
