If demand is not uniform and constant, then stockout risks can be controlled by: 


A. increasing the EOQ.
B. spreading annual demand over more frequent, but smaller, orders.
C. raising the selling price to reduce demand.
D. adding safety stock.
E. reducing the reorder point.

The Correct Answer Is:

D. adding safety stock.

Correct Answer Explanation: D. adding safety stock.

The correct answer to controlling stock-out risks when demand is not uniform and constant is option D, which involves adding safety stock.

Safety stock, also known as buffer stock or reserve stock, is extra inventory held above and beyond the Economic Order Quantity (EOQ) to mitigate the risk of stock-outs when demand fluctuates or unforeseen disruptions occur in the supply chain.

Below, I will provide a detailed explanation of why option D is the correct answer and then explain why the other options are not correct, one by one.

Why Option D (Adding Safety Stock) is Correct:

 Adding safety stock is a prudent strategy for managing stockout risks in a variable demand environment for several reasons:

i. Mitigating Demand Variability:

Safety stock acts as a cushion to absorb fluctuations in demand that can occur due to seasonal changes, market trends, or unforeseen spikes in customer orders.

By having extra inventory on hand, a business can continue to fulfill customer orders during periods of increased demand without experiencing stockouts.

ii. Supply Chain Uncertainties:

It is common for supply chains to face disruptions, such as delays in shipments, unexpected production issues, or transportation problems. Safety stock provides a buffer against these uncertainties, ensuring that there is still inventory available for customers even when supply chain disruptions occur.

iii. Improved Customer Service:

Stockouts can lead to dissatisfied customers and lost sales opportunities. By adding safety stock, a company can maintain a higher level of customer service by consistently meeting customer demand, even in the face of demand fluctuations.

iv. Optimizing EOQ:

Option A suggests increasing the Economic Order Quantity (EOQ) to control stockout risks. However, this is not always the most cost-effective solution. EOQ is designed to minimize ordering and holding costs, but it does not directly account for demand variability.

Increasing the EOQ may lead to higher holding costs and may not adequately address the stockout risk.

Why Other Options are Not Correct:

A. Increasing the EOQ:

While increasing the EOQ may reduce the average holding costs, it may not effectively address the problem of stockouts when demand is variable.

EOQ is primarily focused on finding the most economical order quantity based on fixed order costs and holding costs. Increasing it may not provide the necessary buffer for unpredictable demand fluctuations.

B. Spreading Annual Demand over More Frequent, Smaller Orders:

While this approach may seem intuitive, it may not be the most effective solution for managing stockout risks in a variable demand scenario. While it can help smooth the order pattern, it may lead to higher ordering costs due to the increased frequency of orders.

Moreover, even with more frequent orders, if the total order quantity remains insufficient to meet unexpected spikes in demand, stockouts may still occur.

C. Raising the Selling Price to Reduce Demand:

While adjusting prices can influence demand, it’s important to consider the potential drawbacks of this strategy. Increasing prices may lead to a decline in sales volume and could negatively impact profit margins.

Additionally, it may not directly address the root cause of stockouts related to demand variability. It’s crucial to find a solution that maintains customer satisfaction while also effectively managing inventory levels.

E. Reducing the Reorder Point:

Reducing the reorder point could lead to underordering, which is a risk in itself. A lower reorder point means that orders are placed less frequently, which could result in lower inventory levels and a higher likelihood of stockouts when demand unexpectedly increases.

This strategy may exacerbate stockout risks rather than mitigating them.

In summary, adding safety stock (option D) is the most effective approach to control stockout risks when demand is not uniform and constant. It provides a practical solution to deal with demand variability and supply chain uncertainties, ensuring that customer service is maintained and stockouts are minimized.

The other options do not directly address the problem of stockouts in a variable demand environment and may lead to suboptimal inventory management and potential customer dissatisfaction.
