Refining your integer programming model involves ensuring that your constraints remain accurate and relevant. Here's how you can effectively validate evolving constraints:

• Simulate different scenarios: Test your model with a variety of data sets to see how well it adapts to changing conditions.

• Use sensitivity analysis: Identify which constraints have the most significant impact on the outcomes, and focus on refining these.

• Consult domain experts: Regularly seek input from experts to ensure constraints reflect real-world conditions.
