Municipal Solid Waste (MSW) collection is a necessary process in any municipality resulting in the quality-of-life, economic aspects and urban structuralization. The intrinsic nature of MSW collection relates to the development of effective vehicle routing models that optimize the total traveling distances of vehicles, the environmental emission and the investment costs. In this article, we propose a generalized vehicle routing model including multiple transfer stations, gather sites and inhomogeneous vehicles in time windows for MSW collection. It takes into account traveling in one-way routes, the number of vehicles per m² and waiting time at traffic stops for reduction of operational time. The proposed model could be used for scenarios having similar node structures and vehicles’ characteristics. A case study at Danang city, Vietnam is given to illustrate the applicability of this model. The experimental results have …
