“…This is important for sustained development and eliminating negative environmental impact of transport. Different studies show that cost minimization as a base criteria function is often supplemented by environmental criteria (Molina et al 2014;Salimifard, Raeesi 2014). The routing problems are commonly included into single or multistage localization problems (Szczepański et al 2014) In view of the above, the multicriteria optimization problem of goods distribution in the area of the city was formulated to map real urban transport system.…”

The paper describes proecological solution dedicated for organizing logistics services in urban areas. Proposed solution is based on cross-docking processes combined with consolidation centres. Authors proposed new method of estimating economic and social benefits from implementing centrally managed cooperation of logistics operators using common city consolidation hubs. Developed mathematical model bases on Vehicle Routing Problem (VRP) with vehicles of different types, limited loading capacities and multiply depots characterized by limited throughput. Proposed approach was supported by case study of integration of distribution processes in Warsaw (Poland) performed by three medium-size logistics operators. The central management of distribution was investigated in variants assuming using existing warehouses and with new configuration of logistics network developed with using SIMMAG 3D tools. As it was proved for analysed case, total costs of distribution in the city after implementation of centrally managed distribution were reduced by 8.1% for variant with current depots and by 26.5% for variant with new logistics network, while emission of carbon monoxide (CO) was reduced respectively by 7.8 and 16.7%.

“…These studies can be classified according to the fact that the analysis of the environmental impact and GHG emissions is based on the examination of the given type of fuel [5][6][7][8][9] or the comparison of vehicles using different fuels, such as conventional or renewable energy-based fuel [10][11][12][13][14]. Moreover, research on similar topics often takes into account other aspects, such as driving style [6], consumer preferences related to alternative fuels [15] charging behavior [16], the type of transportation [17][18][19] and the sustainability of transport systems [20,21].…”

Sustainability Investigation of Vehicles’ CO2 Emission in Hungary

et al. 2021

The regulation of vehicular CO2 emissions determines the permissible emissions of vehicles in units of g CO2/km. However, these values only partially provide adequate information because they characterize only the vehicle but not the emission of the associated energy supply technology system. The energy needed for the motion of vehicles is generated in several ways by the energy industry, depending on how the vehicles are driven. These methods of energy generation consist of different series of energy source conversions, where the last technological step is the vehicle itself, and the result is the motion. In addition, sustainability characterization of vehicles cannot be determined by the vehicle’s CO2 emissions alone because it is a more complex notion. The new approach investigates the entire energy technology system associated with the generation of motion, which of course includes the vehicle. The total CO2 emissions and the resulting energy efficiency have been determined. For this, it was necessary to systematize (collect) the energy supply technology lines of the vehicles. The emission results are not given in g CO2/km but in g CO2/J, which is defined in the paper. This new method is complementary to the European Union regulative one, but it allows more complex evaluations of sustainability. The calculations were performed based on Hungarian data. Finally, using the resulting energy efficiency values, the emission results were evaluated by constructing a sustainability matrix similar to the risk matrix. If only the vehicle is investigated, low CO2 emissions can be achieved with vehicles using internal combustion engines. However, taking into consideration present technologies, in terms of sustainability, the spread of electric-only vehicles using renewable energies can result in improvement in the future. This proposal was supported by the combined analysis of the energy-specific CO2 emissions and the energy efficiency of vehicles with different power-driven systems.

“…Erdogan and Miller-Hooks [3] presented a novel formulates and conceptualizes for GVRP regarding the proposed densitybased clustering and modified Clarke and Wright savings heuristic algorithms. Salimifard and Raeesi [4] developed a new routing problem that accounts for optimizing consumption fuel cost and CO 2 emissions by considering main and cleaner alternative fuel. Tiwari and Chang [5] proposed a block recombination model for the GVRP by the goal of minimizing the distance traveled from depot to distribution center.…”

Multi-echelon green open-location-routing problem: A robust-based stochastic optimization approach

2020

In recent years, considering the environmental competencies could help the companies/countries to improve their industries successfully regarding the sustainable development. In this study, a green open location-routing problem with simultaneous pickup and delivery (GOLRPSPD) is considered to minimize the overall costs. In addition to cost minimization, the objective function is provided the environmental competencies regarding the costs of CO 2 emissions and fuel consumptions. Meanwhile, in a complex situation, considering the precise information could lead the results to unreliable in which considering the uncertainty theories could prevent the data loss. In this respect, this study considered the pickup and delivery demand and the travel time as probabilistic parameters. To address the issue, a robust stochastic programming approach is developed to decrease the deviations of imprecise information. Moreover, the proposed approach is implemented based on five scenarios to decide the best decision in different situations. In addition, a practical example of the multi-echelon open-location-routing model is provided to represent the feasibility and applicability of the presented robust stochastic programming approach. Finally, a comparative and sensitivity analysis is considered to indicate the validity of the proposed approach, and also represent the robustness and sensitiveness of the obtained results regarding some significant parameters, respectively.
