Mathematics model for location routing problems with intermediate transfer stations on waste

Product packaging will result in the emergence of waste after the product is used. Management of the waste must be considered so as not to cause loss and damage to nature. The waste management involves a transfer station facility which is a temporary waste disposal site where at this facility, the waste will be processed using existing technology before the waste is finally disposed of at the final disposal site. The model presented in solving the problem of location routing in the waste is multi-objective which comes from the existing literature. The model presented aims to minimize total costs, greenhouse gas emissions and energy consumption levels and the model is able to determine the location and allocation of transfer stations as well as the selection of waste processing technology. To overcome some of the objectives in the problem, a fuzzy programming solution approach is used.
