This repository contains a functional AIMMS example model for Contract Allocation. It demonstrates how to optimize the distribution of demand across various supply contracts while minimizing costs and satisfying business constraints.

In complex supply chains, managing multiple procurement contracts with different pricing tiers, minimum/maximum commitments, and geographical constraints is a challenge. This model helps decision-makers:

• Minimize total procurement costs.
• Respect contractual obligations.
• Balance supply and demand efficiently.

To get the most out of this model, we highly recommend reading our detailed step-by-step guide on the AIMMS How-To website:
