“…In particular, Figure 2.7 shows the elimination of arc (1,3) from the solution and then the selection of arc (5,2) by using the greedy technique of MS; it should be noted that the total number of routes does not change in these iterations. Figure 2.8 and 9 shows, respectively, the elimination of arcs (4,5) and (5,2) from the solution and then the selection of arcs (2,3) and (3,1). Unlike in the previous iterations, Figure 2.10 shows us that, after arc (2,3) is removed from the solution, it can be selected again.…”

Following the emergency caused by the Covid‐19 pandemic, there is the need, among other measures, to modify urban mobility plans in order to reduce the use of collective public transport, reducing the crowding of people while also preventing traffic congestion through discouraging the use of private vehicles. From this perspective, retail companies operating within cities must also reorganize themselves, considering both the unpredictable requirements of environmental sustainability and the new mobility needs calling for the promotion of bicycles and electric scooters. In this context, we deal with the need to determine minimum cost routes in urban areas for delivering orders placed through e‐channels. More precisely, we face a variant of the green vehicle routing problem of heterogeneous fleets, in which the objective function includes environmental impact cost components that differ by vehicle type. Moreover, as a novel issue, attention must be paid to avoid crossing and passing close to bicycle lanes; therefore, penalties are associated with the transit of vehicles near bicycle lanes. To address this problem, we propose a mixed integer linear programming model and a matheuristic associated with it. The proposed approach is then used to analyze different scenarios derived from the transportation network of the city of Milan, Italy. Milan is one of the smartest cities in Europe from the mobility point of view but also one of the most affected by the Covid‐19 pandemic, and the municipality is making a big investment to promote the use of bicycles.

“…The rapid development of industrialization is increasingly worsening the problems of energy shortage and global climate change [1,2]. Stringent regulations related to energy conservation and emission reduction are implemented by governments worldwide to suppress further deterioration of the above problems [3].…”

Negative dwell injection, whose injection rate curves of the two injections partially overlap, is studied along with traditional split injection which is called positive dwell injection with the objective of distinguishing. The injection pressure and ambient pressure are fixed as 60MPa and 1.5MPa. Diffused Background Illumination (DBI) is adopted to photograph the spray behaviors from far and near fields. Based on the far-field results, it is found the spray characteristic of the negative dwell injection is between the single injection and positive dwell injection. Compared with positive dwell injection, the second spray of negative dwell injection can reach the tip of the first spray more rapidly and mix more evenly with each other. Nearfield experiment results confirm the droplets formed near nozzle will hinder the spray penetration of the second injection. For the negative dwell injection, high speed spray of the second injection will suck the droplets left by the first injection, making the spray edge smoother. Violent collision between the first and second sprays for negative dwell injection makes the spray concentration more uniform than other injection strategies. Negative dwell injection can inject more fuel while obtain similar spray characteristics to positive dwell injection within the same time interval.

“…The innovations introduced have been disruptive, especially with respect to new engine technologies and driverless vehicles [8,9]. The European Commission considers green vehicles (a 'green' vehicle is defined as one with emissions intensity that does not exceed 120 g of CO 2 emissions per km [10]) relevant for decarbonizing transport, reducing air pollution, and increasing system efficiency.…”

The Adoption of Green Vehicles in Last Mile Logistics: A Systematic Review

et al. 2020

View full text Add to dashboard Cite

Widespread adoption of green vehicles in urban logistics may contribute to the alleviation of problems such as environmental pollution, global warming, and oil dependency. However, the current adoption of green vehicles in the last mile logistics is relatively low despite many actions taken by public authorities to overcome the negative externalities of distributing goods in cities. This paper presents a comprehensive literature review on studies investigating the adoption of green vehicles in urban freight transportation, paying specific attention to e-commerce. To shed light on the adoption of green vehicles in city logistics, the paper conducts a systematic review of the empirical literature on the topic. The 159 articles reviewed were classified into the following: (a) Optimization and scheduling (67 papers); (b) policy (55 papers); (c) sustainability (37 papers). Among the 159 articles, a further selection of 17 papers dealing with e-commerce, i.e., studies that highlight the most relevant aspects related to the integration of green vehicles in e-commerce urban logistics, was performed. Our findings indicate that green vehicles are competitive in urban deliveries characterized by frequent stop-and-go movements and low consolidation levels while incentives are still necessary for their adoption. The use of autonomous vehicles results the most promising and challenging solution for last-mile logistics.
