Model Matematika untuk Masalah Perutean Lokasi dengan Stasiun Transfer Perantara pada Limbah

Abstract

Product packaging will lead to the emergence of waste after the product is used. The management of the waste must be considered so as not to cause loss and damage to nature. In this waste management, it involves a transfer station fa- cility which is a temporary waste disposal site where at this facility, waste will be processed using existing technology before finally being disposed of in a final dis- posal site. The type of model presented in solving the problem of location routing in the waste is multi-objective which comes from the existing literature. The de- cision variables contained in this model include the volume of waste transported, the technology applied, the number of transport vehicles, and the number of semi- trailers with adapted technology. The model presented has the objective function of minimizing total costs, greenhouse gas emissions and energy consumption levels and the model is able to determine the location and allocation of transfer stations and the selection of waste processing technology. The constraints on the model are the maximum number of transfer stations, the balance of the total amount of waste transported, the limitation of the transfer station capacity, the technology adopted at the transfer station, the minimum percentage of capacity that must be used at each transfer station, the equality of the volume of waste transported with the capacity of the transport vehicle with semi-trailer, and determining the domain of decision variables.
