ABSTRACT

P-median problem has been found to provide optimal solution in a wide range of spatial complexity problems, especially facility location problems. In this paper, the p-median algorithm has been used to deal with the complex problem of zone design. The zone design problem comprises a large number of geographic tasks, from which census zone redistricting, electoral districting, school zone planning. In this paper, a formalization of the census zone problem, suitable for processing by the p-median algorithm is described, and its solution heuristic is tested for different zoning cases. Cooper’s search heuristic, suited to the p-median algorithm is presented together with a p-median objective function. A practical real world example with census output areas is given and tests performed in order to evaluate the effectiveness of the p-median approach.
