Final answer:
The correct answer is 'd. Least total cost (LTC)', as it is not a recognized lot sizing technique within MRP systems. Other options, L4L, EOQ, and LUC, represent legitimate methods for determining optimal order sizes in MRP.
Step-by-step explanation:
The question pertains to lot sizing techniques used in Materials Requirement Planning (MRP). The main answer to the question "All the following are lot sizing techniques in MRP EXCEPT _______ " is option d. Least total cost (LTC). While Lot-for-lot (L4L), Economic order quantity (EOQ), and Least unit cost (LUC) are recognized lot sizing methods employed in MRP for managing inventory and optimizing production orders, the term "Least total cost (LTC)" is not commonly identified as a standard lot sizing technique within the context of MRP.Let's provide an explanation that spans over 100 words to ensure understanding: In MRP, Lot-for-lot is an approach where orders are placed for only what is required for production, minimizing inventory holding costs. The Economic order quantity is a formula used to determine the most cost-effective quantity to order, balancing order costs with holding costs. The Least unit cost method involves ordering at quantities where the unit cost of production or ordering is minimized.In conclusion, LTC is not recognized within the standard slot-sizing methodologies of MRP, and explaining the various methods aids in understanding the complexity and goals of inventory management and production planning.
