A trip factor design for the green vehicle routing: A milk collection process case

Abstract

The total milk production worldwide increased by approximately 1.3% in 2019 compared to the previous year, reaching around 51 million tons. Due to the increase in milk production, global milk imports decreased by 1.3% to 1.4 million tons in 2019, while milk exports increased by 10.5% to 1.9 million tons by TEPGE 2020 dataset. This project aims to enable a dairy and milk-producing business to collect milk from different supply points and return it to the company under the specified constraints, paying attention to fuel consumption and CO2 emissions. It involves creating daily transportation routes, determining which points to collect milk from, the quality of milk to be obtained, and the capacities of the collecting vehicles, all aimed at making the company's resources more efficiently utilized. Based on the provided TEPGE data, milk production increases proportionally with the world population, and with this increase, it is necessary to reach more people. Therefore, it is essential to reduce fuel consumption and CO2 emissions both for the economy and the environment. In this problem, a solution will be developed by incorporating the constraints used in the Milk Collection Problem rather than the conventional Vehicle Routing Problem. The goal is to minimize costs and provide a solution that minimally pollutes the environment for companies engaged in milk transportation.
