Summary

ORPilot is an open-source AI agent designed to solve real-world mathematical optimization problems, addressing the common failure of existing LLM-for-OR tools on complex, data-heavy scenarios. Unlike systems that immediately generate solver code, ORPilot employs a five-stage sequential pipeline: an Interview Agent clarifies ambiguous problem descriptions, a Data Collection Agent specifies data schemas for large datasets, a Parameter Computation Agent derives necessary model parameters from raw data, a Code Generation Agent produces and debugs solver-agnostic Python code for backends like Gurobi or CPLEX, and a Reporter Agent translates results into plain English. This structured approach ensures problem accuracy and data readiness, enabling it to handle large-scale problems, such as a supply chain network design with over 9.7 million decision variables and 963,000 constraints.

Key takeaway

For Operations Professionals or AI Engineers tasked with deploying mathematical optimization models in production, ORPilot offers a robust solution to overcome the limitations of current LLM-for-OR tools. You should consider integrating ORPilot to handle the complexities of real-world data and ambiguous problem statements, ensuring your models are accurately specified and data-ready before code generation. This approach significantly reduces debugging time and improves model reliability for industrial-scale applications.

Key insights

ORPilot's sequential, question-first AI agent approach bridges the gap between LLMs and real-world optimization problems.

Principles

• Prioritize understanding over immediate code generation.
• Treat data as separate from the problem prompt.
• Derive model parameters from raw data automatically.

Method

ORPilot's pipeline involves an Interview Agent, Data Collection Agent, Parameter Computation Agent, Code Generation Agent (with retries), and Reporter Agent, executed sequentially.

In practice

• Use ORPilot for large-scale supply chain optimization.
• Integrate with Gurobi, CPLEX, PuLP, Pyomo, OR-Tools.
• Leverage its data schema and parameter derivation.
