The p-center location problem in an area
WebbOne last area of facility location that requires some discussion is the matter of queueing. So far, the location problem formulations presented all assume one facility can cover all demand without any capacity or congestion delay. This is not the case for many services: emergency medical services, idle taxis or bikeshare, and so on. WebbThe p -centre problem, or minimax location-allocation problem in location theory terminology, is the following: given n demand points on the plane and a weight associated with each demand point, find p new facilities on the plane that minimize the maximum weighted Euclidean distance between each demand point and its closest new facility.
