Abstract In recent years, numerous studies in the field of service quality have been carried out. However, relatively few addressed specific context higher education. The purpose this study has to examine what dimensions constitute education and compare these with that developed general research. focus on academic business a student perspective was chosen. First, 29 in‐depth interviews were Based interviews, questionnaire constructed responses obtained from 448 Austrian Swedish students....
The Steiner tree problem is a challenging NP-hard problem. Many hard instances of this are publicly available, that still unsolved by state-of-the-art branch-and-cut codes. A typical strategy to attack these enrich the polyhedral description problem, and/or implement more and sophisticated separation procedures branching strategies. In paper we investigate opposite viewpoint, try make solution method as simple possible while working on modeling side. Our hypothesis extreme hardness some...
Electric vehicles are prime candidates for use within urban car sharing systems, both from economic and environmental perspectives. However, their relatively short range necessitates frequent rather time-consuming recharging throughout the day. Thus, charging stations must be built system’s operational area where cars can charged between uses. In this work, we introduce study an optimization problem that models task of finding optimal locations sizes stations, using number expected trips...
Online social networks have become crucial to propagate information. Prominent use cases include marketing campaigns for products or political candidates in which maximizing the expected number of reached individuals is a common objective. The latter can be achieved by incentivizing an appropriately selected seed set influencers that trigger influence cascade with maximum impact. In real-world settings, competing spreads need considered frequently. These may, instance, stem from activities...
Climate and weather-related damage have been increasing globally in recent decades. Due to climate change socio-economic developments, a further increase climate-related risks is expected. Numerous countries long successful history disaster risk management (DRM) avoid, minimize manage caused by extreme weather events. In addition, adaptation (CCA) focuses on managing the resulting from today future. To improve effectiveness efficiency of risks, these two independent approaches need be linked...
We introduce the bi-objective prize-collecting Steiner tree problem, whose goal is to find a subtree considering conflicting objectives of minimizing edge costs for building that tree, and maximizing collected node revenues. consider five iterative mixed-integer programming (MIP) frameworks identify complete Pareto front, i.e., one efficient solution every point on front. More precisely, following methods are studied: an ε-constraint method, two-phase binary search in objective space,...
Communication measures can raise protective behavior regarding climate change, natural hazards, and other health risks. For being effective in such communication, we designed a five-steps methodology applied it to health-protective during heat extremes Austria. The five steps are as follows: (1) target group selection, multicriteria assessment (MCA) identify the most important group(s)—this led identification of mobile care nurses our primary group; (2) analysis by interviews drivers...
Concerns about greenhouse gas emissions and government regulations foster the use of electric vehicles. Several recently published articles study vehicles (EVs) in node-routing problems. In contrast, this article considers EVs context arc routing while also addressing practically relevant aspects that have not been addressed sufficiently so far. These include dynamic charging driving, speed-dependent energy consumption, nonlinear functions depend on battery’s state charge time. A generic way...
