[Details of award-winning research]
　This competition is organized by the Japan Material Flow Research Center(JMFI)This is an international competition for students to solve material flow problems, sponsored by theAIとIoT, Efficiency of e-commerce, Global warming and environmental issues, Advanced logistics technology, Logistics DXWith themes such as8University11There was a team entry.
　Based on the spirit of "mottainai," this team aims to contribute to reducing food waste.IoTとAIBy using a data-driven system that utilizes the Internet, we proposed building a smart, temperature-controlled logistics system for the collection and redistribution of surplus food. A unique feature of the system is that it includes temperature-controlled collection and delivery centers and delivery vehicles for food, and allows participants to use a smartphone app to select transportation methods with a low environmental impact in a game-like manner.
