DATA-DRIVEN FOOD SHARING WEB APP SAGANA Connect sponsors and communities
to filipinos in need by creating a community food distribution system based on scheduling and route optimization using web-scraped food and grocery establishments data, poverty statistics and, MRT and LRT ridership statistics
If we can conquer space, we can conquer hunger SAGANA
make food-sharing easy
Q&A
CONSTRAINTS cost controls (more goods in one trip) time windows
(for perishable goods) low risk of queues
SOLUTION Find a set of routes of minimal total traveling
cost and maximal food distributed along BFT's by complying with the prioritized time windows (perishable goods). DISTANCE MATRIX API
HACKING DIJKSTRA'S ALGORITHM 03 Instead of doing Dijkstra's once from
