The ultimate goal of a supply contract is to achieve a win-win outcome for both the buyer and the supplier, where they share the risk and increase the profits of their business relationship12. A supply contract can help achieve this goal by establishing clear and fair terms and conditions that align the incentives, expectations, and responsibilities of both parties34. A supply contract can also help foster trust, collaboration, and innovation between the buyer and the supplier, which can enhance their competitive advantage and customer satisfaction .

* Three-Level Distribution Network: Involves central warehouses, regional warehouses, and retail outlets.
* Risk Pooling: Aggregating inventory at fewer locations to reduce variability in demand and inventory costs.
* Impact of Eliminating a Level:
* Eliminating Regional Warehouses: Direct shipments from central warehouses to retail outlets reduce the aggregation points.
* Decreased Risk Pooling: Fewer aggregation points mean demand variability is less smoothed out, leading to decreased risk pooling benefits.
* Comparison with Other Outcomes:
* Total Transportation Costs (A): Likely to increase due to more frequent direct shipments.
* Retail Outlet Order Frequency (B): Might increase due to more frequent smaller shipments.
* Deliveries to Retail Outlets (C): Likely to increase in number due to direct shipment requirements.
* Conclusion: The most likely outcome is a decrease in risk pooling benefits.
