  1. 1. Critical Decision Factors When Making a Cost-Effective Train Fleet Turnover : A Study in The Swedish Railway Sector

    University essay from KTH/Hållbar produktionsutveckling (ML)

    Author : Roman Zandi; Roy Khazzaka; [2022]
    Keywords : ;

    Abstract : Sustainability and availability are two essential terms for many industries when making changes within the supply chain and making decisions regarding which technical solution is most costeffective and brings the most value to the organization. Since these two topics have been growing in recent years, decision-makers need to understand the level of detail and the value these two areas can bring to an organization. READ MORE

  3. 2. Developing A Network Algorithm for Demand Responsive Transit Service in A Rural Area of Sweden

    University essay from KTH/Transportplanering

    Author : Benny Lam; Peng Shiyi; [2021]
    Keywords : DRT service in rural areas; network algorithm; heuristics algorithm; cost function; Anropstyrd trafik på landsbygden; nätverksalgoritmen; heuristisk algoritm; kostnadsfunktion;

    Abstract : Based on the fact that accessibility in rural areas relies heavily on car traffic, call-driven traffic has been used in different regions to improve public transport usage in rural areas, while it has been difficult to maintain due to high maintenance and long waiting time. Over the past decade, a new demand response transit (DRT) service came into light, which combines with new technologies to provide a more attractive and efficient transport service. READ MORE
