Model. Solve. Deploy. The Advent of OR 2025 is here.

A 24-day email experience to help Operations Research professionals bridge the gap between theory and practice.

Every December, the Advent of OR brings together practitioners, students, and researchers from around the world to tackle one shared challenge. This year, a portfolio rebalancing problem inspired by real business operations.

Over 24 days, participants will:

• Model the problem in GAMSPy, learning how to translate a business scenario into a clear mathematical formulation.
• Solve it with FICO Xpress, exploring solver logic and performance tuning.
• Deploy and test their solution on Nextmv, turning models into decisions that scale.
• Each step is guided by sponsors and experts from across the OR ecosystem, and supported by the global OR community.
• This year’s Advent isn’t just about optimization, it’s about mimicking the full lifecycle of an OR project: framing a problem, building a model, and deploying a solution that drives measurable business value.

Join the challenge and experience what it means to think, build, and communicate like a modern OR engineer.
