A bi-objective Model for the Capacity and Location of Landfills for Municipal Solid Wastes

This paper considers a bi-objective mathematical model for locations of landfills, transfer stations, and material recovery facilities in order to serve the entire regions and simultaneously identify the capacities of landfills. this is a mixed-integer programming (mip) model whose objectives are to minimize the total cost and pollution simultaneously. to validate the model, a numerical example was solved by an augmented s-constraint method, and the associated computational results were presented to show the number of solid waste facilities and location of sites for solid waste facilities.
