FoodFlow: Recommendation & Fulfillment Simulation
A recommendation and fulfillment simulator that jointly models users, merchants, couriers, and platform constraints.
Problem
Food-delivery ranking cannot focus on clicks or conversions alone; it must also account for merchant exposure, fairness, delivery time, supply stability, and courier workload.
Approach
Implemented ranking and reranking strategies, a dynamic dispatch simulator, and a Streamlit/Plotly dashboard for comparing policies, visualizing spatial supply and demand, and explaining recommendations.
Outcome
Built a reproducible experimental workflow for comparing recommendation and fulfillment policies under multiple stakeholder objectives.
