The impact of depot location, fleet composition and routing on emissions in city logistics

Abstract

This paper investigates the combined impact of depot location, fleet composition and routing decisions on vehicle emissions in city logistics. We consider a city in which goods need to be delivered from a depot to customers located in nested zones characterized by different speed limits. The objective is to minimize the total depot, vehicle and routing cost, where the latter can be defined with respect to the cost of fuel consumption and CO2 emissions. A new powerful adaptive large neighborhood search metaheuristic is developed and successfully applied to a large pool of new benchmark instances. Extensive analyses are performed to empirically assess the effect of various problem parameters, such as depot cost and location, customer distribution and heterogeneous vehicles on key performance indicators, including fuel consumption, emissions and operational costs. Several managerial insights are presented.

The Effect of Environmental Criteria on Locating a Biorefinery: A Green Facility Location Problem

“…Ortiz-Astorquiza et al (2015) did a theoretical study on the multi-level FLP, which mainly consists of finding the best set of facilities to open for each level in order to maximize the total profit, satisfying the demand of every customer. Another FLP variant is the Location Routing Problem in which an FLP and a Vehicle Routing Problem are considered at the same time (Koç et al, 2016). A rich collection of multi-objective FLP literature can be explored, such as Bashiri and Rezanezhad (2015) and Gutjahr and Dzubur (2016).…”

Análise dos benefícios de um espaço logístico urbano na distribuição urbana de mercadorias

“…Os resultados foram analisados na perspectiva econômica, operacional, ambiental, social e da eficiência energética, e permitiram identificar fatores chaves para a implantação deste tipo de sistema, como a densidade comercial na área. Koç et al (2016) analisam o impacto da localização de armazéns, composição da frota e roteamento na emissão de poluentes e entregas urbanas.…”

A robust green traffic‐based routing problem for perishable products distribution

“…In the classic VRP, the goal is to find an optimal set of routes for vehicle fleets to service a certain number of customers and minimize total traveling cost, whereas the GVRP seeks to minimize total fuel consumption and CO 2 emissions in addition to the stated objectives . In recent years, green transportation has been attracting the attention of many operational researchers aimed at ameliorating environmental sustainability by reducing fuel consumption throughout transportation systems . The GVRP has been recently studied for the targets such as the optimal assignment of different vehicles to delivery nodes to reduce CO2 emissions and optimal routing of a heterogeneous fleet of vehicles in urban logistics .…”

“…4 In recent years, green transportation has been attracting the attention of many operational researchers aimed at ameliorating environmental sustainability by reducing fuel consumption throughout transportation systems. [5][6][7][8] The GVRP has been recently studied for the targets such as the optimal assignment of different vehicles to delivery nodes to reduce CO2 emissions and optimal routing of a heterogeneous fleet of vehicles in urban logistics. 9 One of the proposed methods for reducing CO2 emissions and fuel consumption is to make optimal routing decision on when and how often customers must be served.…”
