Municipal solid waste management is a paramount activity in modern cities due to environmental, social and economic problems that can arise when mishandled. In this work, the sequencing of micro-routes in the Argentine city of Bahía Blanca is addressed, which is modelled as a vehicle routing problem with travel time limit and the vehicle's capacity. Particularly, we propose two mathematical formulations based on mixed integer programming and we solve a set of instances of the city of Bahía Blanca based on real data. Moreover, with this model, we estimate the total distance and travel time of the waste collection and use this data to analyse the possibility of installing a transfer station. The results demonstrate the competitiveness of the approach to resolve realistic instances of the target problem and suggest the convenience of installing a transfer station in the city considering the reduction of the travelled distance.
城市固体废物管理是现代城市至关重要的活动，因为如果处理不当，可能会产生环境、社会和经济问题。在这项工作中，我们研究了阿根廷布兰卡港的微路径排序问题，该问题被建模为具有旅行时间限制和车辆容量的车辆路径问题。具体而言，我们提出了两种基于混合整数规划的数学模型，并基于实际数据解决了一组布兰卡港的实例。此外，我们使用该模型估计了垃圾收集的总距离和旅行时间，并使用这些数据来分析安装转运站的可能性。结果表明，该方法解决目标问题实际实例的竞争力，并建议考虑到行驶距离的减少，在城市中安装转运站的便利性。
