Clustering, location, and allocation in two stage supply chain for waste management: A fractional programming approach

In this paper, we deal with waste management. Our modelling proposal is to use fractional programming to solve two strategical objectives related to the costs incurred and utility generated in servicing customers when clustering, location, and allocation are performed on the supply chain associated with the considered waste management problem. To the best of our knowledge, this is the first model in the literature acting in these directions. After describing the fractional model and its rationale, we apply a reformulation of the latter in terms of mixed-integer linear programming. Experiments carried out after its implementation reveal that the model is effective in producing high quality solutions for the problem.
