ITPEC IP April 2024 Question 86
Which of the following is the situation where an improvement can be expected by installing an MRP (Material Requirements Planning) system?
Explanation
Material information is insufficient or incorrect, so production suffers — the problem MRP solves.
MRP (Material Requirements Planning) starts from the production schedule for finished products and uses the bill of materials to explode it into the parts and materials each one needs. It subtracts the inventory on hand and on order to get the net requirement, then offsets it by the lead time to show what to order, how many and when. Missing or wrong material information is exactly what this calculation replaces.
Answer (b)
Why not others:
- •(a) — keeping drawings and their change history consistent is a document or product data management problem, not a material calculation
- •(c) — frequent design changes lower efficiency at the design stage; MRP recalculates requirements but does not reduce the changes
- •(d) — the rising cost of production equipment for high-mix, low-volume production is an investment issue that MRP does not address
Key rule: MRP turns the production plan into time-phased net requirements: gross requirement from the bill of materials, minus inventory, ordered one lead time ahead.
