- Abstract: Over 44 million Americans currently suffer from food insecurity, of whom 13 million are children. Across the United States, thousands of food banks and pantries serve as vital sources of food and other forms of aid for food insecure families. By optimizing food bank and pantry locations, food would become more accessible to families who desperately require it. In this work, we introduce a novel two-level optimization framework, which utilizes the K-Medoids clustering algorithm in conjunction with the Open-Source Routing Machine engine, to optimize food bank and pantry locations based on real road distances to houses and house blocks. Our proposed framework also has the adaptability to factor in considerations such as median household income using a pseudo-weighted K-Medoids algorithm. Testing conducted with California and Indiana household data, as well as comparisons with real food bank and pantry locations showed that interestingly, our proposed framework yields food pantry locations superior to those of real existing ones and saves significant distance for households, while there is a marginal penalty on the first level food bank to food pantry distance. Overall, we believe that the second-level benefits of this framework far outweigh any drawbacks and yield a net benefit result.

The impact of online food delivery platforms on users' healthy food choices remains unclear.
Male, low-income, and younger users and those located in larger cities more likely to order fast food via O2O platforms.
A higher ratio of fast food orders is associated with "cyber food swamps", areas characterized by a higher share of accessible fast food restaurants.

We partner with a non-profit organization in the state of Indiana that leads emphFood Drop, a program that is designed to redirect rejected truckloads of food away from landfills and into food banks.
Our goal in this partnership is to completely automate Food Drop.
In doing so, we need a matching algorithm for making real-time decisions that strikes a balance between ensuring fairness for the food banks that receive the food and optimizing efficiency for the truck drivers.
