In the case of logistic companies, using efficient and optimized route for delivery reduces transport costs. We adopted this idea to reduce transport maintenance cost. So we divide this into two steps.
We divided 40 districts as the maximum operation of school cafeteria is about 1500 people. We used K-nearest-Neighbors to predict the district. We used two ways to divide the district. First, we used physical distance from the schools. Also, we used weighted K-nearest Neighbors by student population. Both districts are similar, so we decided to divide the district by population as the capacity of delivery services and workforce is important.
We attatched our route optimization code that used T map API.
According to the report from the Bank of Korea, the population working from home will be maintained after the pandemic situation. We expand our service to young 20s who live alone and work from home, who wants to eat fresh and balanced meals and maintain the population size for each production batch(school).
To find this new customer target, we had to find some districts where our strategy could work.
