Round 114

Inventory Fulfillment Architecture

The central distribution hub for a mid-sized e-commerce retailer is reaching capacity. To maintain 2-day delivery SLAs while managing rising logistics costs, the operations team must decide on a fulfillment scaling strategy for the next fiscal year. Constraints include a fixed capital expenditure budget and a requirement to minimize customer-facing errors during the transition. Tradeoffs involve balancing inventory carrying costs vs. shipping speeds, and central control vs. regional flexibility.
