Planning the distribution of goods in the context of city logistics considering split deliveries with access and time restrictions

摘要

>Cities are getting bigger with more homes and companies which demand more goods to supply them. Furthermore, more vehicles are travelling in the cities which lead to an increase of greenhouse gas emissions, traffic jam and many other problems that damage the citizens' quality of life. To make it better, local governments are imposing restrictions on the type of vehicles and the time that they can deliver goods in the city. Thus, to plan the distribution of goods in this restricted context, this paper proposes a mathematical model that incorporates the characteristics of split deliveries, heterogeneous fleet, access restrictions and time windows for planning the distribution of goods. Based on real data from an agricultural supply company that delivers goods to supermarkets, seven instances were elaborated and the results showed that the model can bring cost savings for the company and environmental benefits for the citizens.
