19. How does capacity requirements planning (CRP) differ from rough-cut capacity planning (RCCP)?
Answer: A
CRP uses actual planned orders, instead of assumed orders.
Capacity requirements planning (CRP) focuses on the actual planned orders that are in the system, allowing for a precise determination of capacity needs. This contrasts with rough-cut capacity planning (RCCP), which may operate based on assumed orders for a general overview of capacity.
A) CRP uses actual planned orders, instead of assumed orders.
This statement accurately describes the primary function of CRP. By relying on actual planned orders, CRP provides a more accurate assessment of capacity requirements, ensuring that manufacturing resources are aligned with confirmed production schedules.
B) CRP uses assumed orders, instead of actual planned orders.
This option is incorrect as it misrepresents the nature of CRP. CRP is specifically designed to utilize actual planned orders to create an accurate forecast of capacity needs, rather than relying on assumptions that could lead to miscalculations.
C) CRP does not use released manufacturing orders.
This statement is misleading. CRP does incorporate released manufacturing orders as part of its process, as it needs to account for all confirmed orders in order to calculate the necessary capacity accurately.
D) CRP does not use either planned and assumed orders.
This option is incorrect. CRP fundamentally relies on planned orders, specifically actual planned orders, to evaluate capacity requirements, making this statement inconsistent with the core definition of CRP.
Conclusion
The correct answer, A, highlights the critical distinction that CRP operates based on actual planned orders, ensuring an accurate assessment of capacity needs. All other options either misrepresent the function of CRP or incorrectly state its reliance on different types of orders, thus failing to capture the essential characteristics of capacity requirements planning.
