Problem Statement 1
"Optimization of Food Supply"

In 2050, the global population grows up to 9.8 billions, and food supply is required to be increased by 60% to satisfy all. But in fact, the curerent food output is already enough. The problem is "supply chain".

How might we optimize the food supply chain for sustainable future? Please share with us your ideas!

Problem Statement 2
"Unleashing the power of data and information"

The accuracy and reliability of information and data has bee increasingly important. In this context, we would like to explore the possibility of building new business models in the B2B or B2B2C areas by utilizing the unique information and data possessed by us. You do not need to stick to below items but here are the examples of our problems statements.
1) How might we use data and information for better cash flow forecasting?
