DRIVER SELECTION

Jamaica Plain Pastry Co → Jamaica Plain Community Fridge

This route is the best overall available match for this driver, bakery, and pantry. Other routes shown are alternatives, not rejected trips.

MODEL COMPARISON

One illustrative scenario, five routing approaches

Every approach sees the same 5-day scenario.

↔

Same scenario, different priorities.

Each approach puts more emphasis on a different goal, such as pantry coverage, environmental impact, fair distribution, or volunteer choice. The results show those trade-offs side by side.

OPTIMIZATION POLICY

BakedBoston Gurobi MIP

Maximizes one acceptance-adjusted expected-impact objective across simultaneous drivers, balancing food, fairness, environment, pantry priority, and driver fit.

COMPARISON POLICY

Nair et al. coverage-first adaptation

A minimal volunteer-route adaptation of the 2018 periodic unpaired pickup-and-delivery model: protect distinct pantry service first, then completed pickups and miles.

Read the source study ↗
COMPARISON POLICY

Xue–Zou Total-Curb adaptation

A minimal volunteer-route adaptation of the 2025 Total-Curb model: protect service first, then minimize total direct system CO2e.

Read the source study ↗
COMPARISON POLICY

Horner et al. stochastic-menu adaptation

A minimal adaptation of the 2021 SLSF-noZ model: optimize short personalized menus over seeded stochastic willingness scenarios, then assign among routes drivers are willing to fulfill.

Read the source study ↗
COMPARISON POLICY

Rey et al. equitable-allocation adaptation

A deliberately limited adaptation of the 2018 food-rescue allocation work: protect completed pickup service, then minimize the maximum gap in cumulative ultimately distributed food across pantries.

About this comparison

Every model sees the same simulated day, so the results show how different routing priorities create different outcomes.

Use the detailed metrics to explore the trade-offs. The source-study links describe each comparison approach in depth.

HOW THE SIMULATOR WORKS

Compare practical routes by their community impact.

What you are seeing

The simulator creates a shared, synthetic food-rescue day and asks each approach to make route decisions. BakedBoston checks whether a route can happen, then weighs food recovery, pantry service, environmental impact, and volunteer practicality.

The comparison is designed to show trade-offs, not to declare a single universal winner. It does not contact real partners or issue delivery assignments.

A full technical paper will be linked here when it is complete.
