🔄Delays Make Systems Oscillate: Simulating Inventory Management
Longer delays can stabilize inventory systems
TL;DR
New research shows that increasing the delay between customer demand and system response can prevent overreaction to spikes. For a system with initial daily sales of 20 cars, lengthening the delay stabilizes behavior without causing shortages.
Research reveals that delays in responding to customer demand can actually stabilize inventory management systems. Initially set at 2 days, changing the response delay divisor to 6 reduced oscillations and prevented overreaction to spikes. This is crucial for teams managing stock levels, especially when dealing with unpredictable demand surges like a spike of 70 cars on one day. The study uses a Monte Carlo simulator or spreadsheet model to demonstrate that longer delays can prevent inventory shortages without compromising customer satisfaction.
Key Points
Customer demand starts at 20 cars per day, then increases to 22 cars daily with a spike of 70 cars on one specific day
The delivery delay is fixed at 5 days, affecting how quickly new inventory arrives
Sales are the minimum between customer demand and available inventory
Desired inventory is calculated as sales multiplied by 10 to ensure stock levels meet future needs
Response delay divisor was adjusted from 2 to 6 to stabilize system behavior
Why It Matters
If you're managing a supply chain with unpredictable spikes in demand, lengthening the response delay can prevent overreaction and oscillations. For instance, a company selling cars online might see daily sales of 20 units but face sudden surges like a spike to 70 units on one day. By adjusting the inventory update cycle from every two days to six days, they can stabilize stock levels without risking shortages or excess.
