Abstract :

Vehicle routing problem (VRP) is the act of minimizing total traveled distance and travel time to dispatch products with same or different capacitated vehicles from a central depot to customer’s locations. However, companies aim to decrease fuel consumption to reach cost advantage over rivals and constitute a better image among environmental considered customers. As a new variant of VRP, “green vehicle routing problem (GVRP)” aims, unlike the conventional approach, to design a route in consideration of environmental factors such as fuel consumption and gas emission. Increased environmental consideration in legal and social contexts addressed the factors that affect the environment in vehicle routing problem. Thus, a sustainable distribution network could be designed with less energy consumption and fewer negative impacts on the environment. The purpose of this study is to develop a comprehensive literature review in a popular topic within academic and industrial areas known as green capacitated vehicle routing problem. The scope of literature review consists of 57 articles published between 2007 and 2016. This literature provides major benefits to academic studies in four ways: (i) presenting a detailed investigation about the articles focused on GCVRP, (ii) evaluating the factors that affect the fuel consumption and gas emissions, (iii) determining the solution method for GCVRP, (iv) presenting several suggestions about future works.
