Abstract: Waste management is a complex and broad field of research. Several decision-makers have conflicting objectives and hierarchies in problems falling under this category. Therefore, the common single-objective or multi-objective optimisation approaches may fail to capture the nuances of the situation. Hierarchical problems are best handled from a mathematical optimisation point of view via bilevel programming. In this paper, we survey contributions modelling waste management issues employing bilevel optimisation, a relatively new yet promising field of research. We start by providing a general analysis of these contributions and then describe the latter in macro-subjects. Finally, we draw some conclusions by providing open problems and follow-ups.

Keywords: bilevel optimisation; waste management; literature review.
