Feasibility analysis of super-speed rail based on improved value function

Abstract

Abstract Super-speed rail (SSR) is a kind of train design based on the theory of vacuum pipeline transportation, having the advantages of super speed, high safety, low energy consumption, low noise, no vibration and no pollution. SSR may be a new generation of trains after cars, ships, trains and aeroplanes. The SSR system includes two parts, namely vacuum pipe technology and magnetic levitation technology. Based on the definition of SSR, the present paper analyses the operation principle of SSR. According to distribution characteristics of SSR, the evaluation index system of SSR was set up. In analysing the main characteristics of SSR, this paper builds the evaluation model by improved value function. The application results validate the feasibility of the new method in comprehensive evaluation for SSR. It is consistent with the results of other methods. The result reveals that SSR is completely feasible from a theoretical point of view and it is impossible to build SSR in a short time from the application perspective. The evaluation results can reflect the actual situation. The comprehensive evaluation model is scientific and the process is simple.
