Abstract: In this paper, we show an application of bilevel programming to the problem of locating waste collection centres inside a municipal area. In our study, the latter problem possesses a hierarchical structure, i.e., there are two decision makers, one of which acts as a leader and the other behaves as a follower. Therefore, we exhibit a bilevel optimisation program able to capture this hierarchy and propose an iterative algorithm to solve the problem. This solution proposal is then tested on data derived from a real scenario. Experimental results reveal that the approach is effective in this kind of decision problems.
