| Sumario: | This paper focuses on determining the raw milk collection routes with heterogeneous fleet aiming to minimize the average operational emissions of carbon dioxide. The problem is a particular case of the Vehicle Routing Problem (VRP) which considers the variation of emissions in terms of load and distance. Two types of the problem are studied, one in which the routes of the available fleet are optimized, and another which determines the configuration of the fleet and its routes. For solving the problems, an exact method based on a Branch and Bound formulation and a multi-start heuristic based on the Iterated Local Search (ILS) are implemented. Randomly generated instances were implemented inspired by the conditions of the Ubaté-Chiquinquirá dairy region in central Colombia, considered one of the five largest milk producers with the highest daily productivity. The instances have a combination of different factors which are: the location of the processing plant, the farms in clusters, and the number of farms. The analysis reveals that in terms of route design, an environmental approach can produce an increase in the distance traveled by vehicles (up to 60%) while reducing the overall emissions, and also the importance of replacing part of the large and polluting vehicles with smaller vehicles with lower emissions. The results may facilitate decision-making, provide insights for shifting to sustainable approaches in routing problems, and suggest future works |
