Decision-Making Model of Urban Rail System for Operation Optimization and System Upgrading

Urban rail transport is an efficient and environmentally friendly transport solution.However, there are many challenges due to weak power supply and high capacity demand.To reduce energy consumption, minimize operational costs and increase transport capacity, there are many possible solutions to achieve these goals.It is needed to make a smart and cost-effective plan for efficiently using infrastructure as well as saving energy.This paper proposes a decision-making model to demonstrate the effectiveness of different technical solutions and quantify their costs and benefits on the energy and capacity aspects for comparison.Based on the model, two case studies on the Stockholm commuter trains and metro trains with several technical solutions as examples are analyzed.The model is supposed to provide a key reference for decision-makers to set up a smart and cost-effective management plan for efficiently using infrastructure as well as saving energy.
