Problem Formulation- Candidate locations for kitchens and cross docking facilities
66 cities within Uttar Pradesh- Customers
1076 blocks (157 schools on average with 50 kids in each school)- Data
66 by 1076 matrix each for distance and time (each city to each block)
Goal:MINIMIZE Kitchen set up cost + Delivery cost Subject to Constraints- Demand, Supply, Time, Co-location, Flow conservation

Limitations - Truck Size- Truck Utilization (36% are under utilized)- Decentralized kitchen- Cross docking cost- Cost of insulated containers - Cost of inbound transportation- Cost of setting up kitchens in different locations

Conclusion
From our analysis, we found that investing in - insulated containers (increasing the food serving time limit from four to six hours) along with - consolidated deliveries within cities provides the most attractive solution (Scenario 6)*
* Remember the model considers upfront fixed cost and 1 day of delivery cost
