Definition
An optimal location query concerns three spatial point sets on a road network: a set F of facilities, a set C of clients, and a set P of candidate locations. The objective of this query is to identify a candidate location p ∈ P, such that a new facility built at p can optimize a certain cost metric that is defined based on the network distances between the facilities and the clients. Optimal location queries find important applications in the strategic planning of resources (e.g., hospitals, post offices, banks, retail facilities) in both public and private sectors (Cabello et al. 2005; Du et al. 2005; Zhang et al. 2006). As an example, we illustrate three optimal location queries based on different cost metrics.
Example 1.
Julie would like to open a new supermarket in San Francisco that can attract as many customers as possible. Given the set F (resp. C) of all existing supermarkets (resp. residential locations) in the city, Julie may look for a candidate location p, such...
