1. Which inventory model aims to determine the optimal order quantity that minimizes total inventory costs?
a) Economic order quantity model
b) Quantity discount model
c) Stochastic inventory model
d) Multi-product model
Answer: a) Economic order quantity model
Explanation: The Economic Order Quantity (EOQ) model calculates the ideal order quantity that minimizes the total inventory costs, considering factors like holding costs and ordering costs.
2. In which inventory model are quantity discounts taken into account to determine the optimal order quantity?
a) Economic order quantity model
b) Quantity discount model
c) Stochastic inventory model
d) Multi-product model
Answer: b) Quantity discount model
Explanation: Quantity discount models consider discounts offered by suppliers for ordering larger quantities and aim to determine the order quantity that maximizes cost savings, balancing holding and ordering costs with the discounts.
3. Which inventory model considers uncertain demand and lead times in inventory management?
a) Economic order quantity model
b) Quantity discount model
c) Stochastic inventory model
d) Multi-product model
Answer: c) Stochastic inventory model
Explanation: Stochastic inventory models account for variability in both demand and lead times, allowing for more robust inventory management strategies in the face of uncertainty.
4. Which inventory model deals with managing inventory for multiple products simultaneously?
a) Economic order quantity model
b) Quantity discount model
c) Stochastic inventory model
d) Multi-product model
Answer: d) Multi-product model
Explanation: Multi-product inventory models involve optimizing inventory levels across multiple products, considering factors such as demand variability, production constraints, and storage capacities.
5. What type of inventory model incorporates real-world constraints and operational considerations into inventory management strategies?
a) Economic order quantity model
b) Quantity discount model
c) Stochastic inventory model
d) Inventory control models in practice
Answer: d) Inventory control models in practice
Explanation: Inventory control models in practice integrate various real-world constraints, such as production capacity, storage limitations, and supplier reliability, into the inventory management process for more practical and effective solutions.
6. Which inventory model focuses on determining the optimal reorder point and order quantity based on probabilistic demand and lead time distributions?
a) Economic order quantity model
b) Quantity discount model
c) Stochastic inventory model
d) Multi-product model
Answer: c) Stochastic inventory model
Explanation: Stochastic inventory models utilize probabilistic demand and lead time distributions to calculate the optimal reorder point and order quantity, considering the uncertainty inherent in these variables.
7. Which inventory model is primarily concerned with minimizing the total cost of inventory, including holding and ordering costs?
a) Economic order quantity model
b) Quantity discount model
c) Stochastic inventory model
d) Multi-product model
Answer: a) Economic order quantity model
Explanation: The Economic Order Quantity (EOQ) model aims to minimize the total cost of inventory by finding the order quantity that balances holding costs (inventory carrying costs) with ordering costs.
8. Which inventory model focuses on optimizing inventory levels while considering discounts offered for purchasing larger quantities?
a) Economic order quantity model
b) Quantity discount model
c) Stochastic inventory model
d) Multi-product model
Answer: b) Quantity discount model
Explanation: Quantity discount models aim to optimize inventory levels by taking into account discounts offered for purchasing larger quantities, ensuring cost-effective inventory management.
9. Which inventory model is suitable for businesses dealing with multiple products and varying demand patterns?
a) Economic order quantity model
b) Quantity discount model
c) Stochastic inventory model
d) Multi-product model
Answer: d) Multi-product model
Explanation: Multi-product models are suitable for businesses managing inventories of multiple products with diverse demand patterns, allowing for efficient inventory management across the product portfolio.
10. Which inventory model accounts for random fluctuations in demand and lead times, helping to mitigate the risk of stockouts?
a) Economic order quantity model
b) Quantity discount model
c) Stochastic inventory model
d) Multi-product model
Answer: c) Stochastic inventory model
Explanation: Stochastic inventory models consider random variations in both demand and lead times, enabling businesses to set appropriate reorder points and order quantities to minimize the risk of stockouts while controlling inventory costs.
