Multi-Objective Model for The Selection of The Optimal Solid Waste Transfer Station Locations and for The Identification of The Optimal Transport Scenario

A multi-objective optimization model with binary variables is presented. This model can be used for the selection of the optimal solid waste transfer station locations and identifying an optimal transport scenario to minimize total cost, the number of vehicles required and greenhouse gas emissions generated by the transport of waste and providing information about the number, locations and capacities of operational transfer stations, the number of waste transport vehicles required, number of round trips and the road traffic generated in each waste transport trajectory. The model is programmed using Matlab and is applied to a hypothetical example. The model offers a graphical representation for the results of different possible transport scenarios verifying the conditions set to compare between them and choosing the desired scenario according to the user's interpretations of the results.
