“…These were taken from empirical taxi data that was analyzed for a German metropolitan area in Ehmke et al . We assume a driver's salary is $11.46 per hour and a fuel price of $1.19 per liter, based on information from Ehmke et al . Each instance is computed 5 times on 2.6‐GHz Intel Xeon processors with 512 GB of RAM, and we report the best result of the 5 runs.…”

Impact of congestion pricing schemes on costs and emissions of commercial fleets in urban areas

As urbanization increases, municipalities across the world have become aware of the negative impacts of road-based transportation, which include traffic congestion and air pollution. As a result, several cities have introduced tolling schemes to discourage vehicles from entering the inner city. However, little research has been done to examine the impact of tolling schemes on the routing of commercial fleets, especially on the resulting costs and emissions. In this study, we investigate a vehicle routing problem considering different congestion charge schemes for several city types. We design comprehensive computational experiments to investigate whether different types of tolling schemes work in the way municipalities expect and what factors affect the performance of the congestion charge schemes. We compare the impact on a company's total costs, fuel usage (which drives emissions), and delivery tour plans. Our experimental results demonstrate that some congestion pricing schemes may even increase the emissions in the city center, and higher congestion charges may not necessarily lead to lower emissions.

“…Bektas y Laporte (2011) propusieron un modelo de VRP para las emisiones de carbono, analizando su impacto en la función de costo total, considerando variantes con o sin ventanas de tiempo. Otros estudios relevantes han analizado el uso de la flota heterogénea desde una perspectiva del GVRP (Koç et al, 2014(Koç et al, , 2016Kopfer et al, 2014), el uso de flotas de vehículos eléctricos (Felipe et al, 2014;Goeke y Schneider, 2015;Juan et al, 2014;Yang y Sun, 2014), la planificación de los sistemas de recogida de residuos reciclables teniendo en cuenta las preocupaciones económicas y medioambientales (Ramos et al, 2014) y las emisiones asociadas con viajes dependientes del tiempo (Ehmke et al, 2015;Qian y Eglese, 2016). La mayor parte de estos trabajos consideran que la reducción de la distancia recorrida es la mejor manera de reducir el consumo de combustible y las emisiones.…”

_____________________________________________________________________________________________________________________________________ ResumenEste trabajo aborda un problema de enrutamiento de vehículos en ciudades de montaña, para determinar la más óptima. Actualmente el transporte verde se ha convertido en un tema de gran interés debido a su relación directa con el costo operativo y su impacto en el medio ambiente. Tradicionalmente se ha considerado que la ruta más corta minimiza tanto costos como emisiones. Sin embargo, la topografía del terreno en montañas es una particularidad que debe ser considerada con miras a lograr soluciones más acordes con la realidad. Para este estudio, se propone un modelo matemático multiobjetivo, el cual determina una ruta que logra un adecuado balance entre el costo del transporte y el impacto ambiental. El modelo se aplicó en un canal de distribución minorista de una ciudad andina de Colombia. Se concluyó que, en escenarios de montaña, la ruta más corta no es necesariamente la mejor, debido al impacto de la pendiente en el consumo de combustible y en las emisiones de CO2. Palabras clave: enrutamiento de vehículos; consumo de combustible; emisiones de CO2; pendiente de la carretera; multiobjetivo A Vehicle Routing Solution for Hilly Cities Considering Environmental and Economic Issues AbstractThis paper addresses a vehicle routing problem in mountainous cities with the objective of finding the optimum route. Currently, green transportation has become a topic of great interest due to its direct relation with operational costs and its impact on the environment. Traditionally, the shortest route has been considered to minimize both costs and emissions. However, topography in mountains is a particularity that must be considered in order to achieve more realistic solutions. For this study, a multi-objective mathematical model is proposed to determine a route that achieve a proper balance between transportation cost and environmental impact. The model was applied in a retail distribution channel of an Andean city in Colombia. It was concluded that in mountain scenarios, the shortest route is not necessarily the optimum, due to the impact of slope on fuel consumption and CO2 emissions.

“…Similar to scheduling and rescheduling problems, equity and emissions are also observed in the field of VRP when the decision-makers aim to build green logistic strategies, and thus the studies concerned with the reduction of emission have emerged in recent years [178,180,200,[213][214][215].…”

Over the past decades, optimization in operations management has grown ever more popular not only in the academic literature but also in practice. However, the problems have varied a lot, and few literature reviews have provided an overview of the models and algorithms that are applied to the optimization in operations management. In this paper, we first classify crucial optimization areas of operations management from the process point of view and then analyze the current status and trends of the studies in those areas. The purpose of this study is to give an overview of optimization modelling and resolution approaches, which are applied to operations management.
