The standard p-median problem seeks to find an optimal location for a number of p facilities considering a distribution of demand points. On the above representation of an isometric landscape, the p-median problem can be considered by:
- Number of facilities. The minimum is one facility (p=1). The higher the number of facilities, the less the average transport cost or distance a user travels to be serviced.
- Weighted or unweighted. In an unweighted scenario, each demand point is of similar importance, while a weighted scenario considers that demand points can be of different importance.
