A system is provided that designs a supply chain network. The system identifies a service level agreement metric definition. The system further generates a grid including cells, where the grid is located over a representation of a geographical region. The system further computes a service level agreement metric for each cell of the grid using the service level agreement metric definition. The system further selects cells that have the largest service level agreement metrics and that have not been previously selected. The system further positions a supply chain network resource at a center of the selected cells. The system further computes a service level agreement based on the service level agreement metric of the selected cells.
