Tralhão et al. [26] propose a 1/P/multiwaste/TC,FC,multiobj MIP
approach to identify the locations and capacities of multicompartment
sorted waste containers. The model aims at determining
the number of facilities to be opened, as well as the
respective container capacities, their locations, and the dwellings
assigned to each facility. The solution approach integrates an
optimization model in a Geographical Information System-based
interactive decision support system with the aim of minimizing
the following four objectives: (1) the total investment cost; (2) the
average distance from dwellings to the respective multicompartment
container; (3) the number of individuals too close
to any containers; (4) the number of dwellings too far from the
respective multi-compartment container. The proposed approach
is tested on a case study raised the city of Coimbra (Portugal).
