A more efficient cutting planes approach for the green vehicle routing problem with capacitated alternative fuel stations

2021

AbstractThe Green Vehicle Routing Problem with Capacitated Alternative Fuel Stations assumes that, at each station, the number of vehicles simultaneously refueling cannot exceed the number of available pumps. The state-of-the-art solution method, based on the generation of all feasible non-dominated paths, performs well only with up to 2 pumps. In fact, it needs cloning the paths between every pair of pumps. To overcome this issue, in this paper, we propose new path-based MILP models without cloning paths, for both the scenario with private stations (i.e., owned by the fleet manager) and that with public stations. Then, a more efficient cutting plane approach is designed for addressing both…

Renewable sources and its applications awareness in educational institutions

2019

The topic of the presented research was to analyze the awareness on renewable energy sources among the students of three universities: the Ural Federal University (Russia), the University of Trento (Italy) and Lucian Blaga University of Sibiu (Romania). The survey included 6 basic multiple-choice questions about the main points of the renewable energy topic. Data were collected and analyzed in aid of percentage ratio of right answers among students on each possible answer. The approach adopted in the three universities for the education on topics related to renewable energy is different. This difference explains the different point of view of students on renewable energy.
