Special Inventory Models

Flashcards covering key concepts related to Special Inventory Models, including definitions and important terms.

Noninstantaneous Replenishment

Refers to a situation where maximum cycle inventory is less than the lot size (Q), and the item can be used or sold as it is produced.

Production Rate (p)

The rate at which items are produced, typically expressed in units per time period.

Demand Rate (d)

The rate at which items are used or sold, also expressed in units per time period.

Economic Production Lot Size (ELS)

The optimal lot size that minimizes the total annual cost, resulting in a larger lot size than the Economic Order Quantity (EOQ).

Time Between Orders (TBO)

The cycle length or the duration between successive orders in inventory management.

Cycle Inventory

The average inventory used in the process that fluctuates based on production and demand.

Quantity Discounts

Price incentives offered to encourage the purchase of larger quantities, affecting inventory management strategies.

Annual Holding Cost

The total cost associated with storing inventory over a year, typically expressed as a percentage of the inventory's unit price.

Annual Ordering Cost

The total cost incurred in ordering inventory, including setup costs and order placement costs.

Total Annual Cost (C)

The total expense incurred for holding and ordering inventory, calculated as: Annual holding cost + Annual ordering cost + Annual cost of materials.
