Train Operation of Multi-Objective Optimization
Abstract: In recent years, the demand for railway transportation is increasing and the railway
transportation has been developed faster and faster. The traditional railway has lower speed and
much more energy. During the operation of the train, not only we should ensure the safety of
operation but also consider the comfort of the passengers. Therefore we need to optimize the
operation of the train. In this paper, the single particle motion model is adopted and builds a
model to describe the interval operation of the train. During the operation, there are three
control strategies such as traction, coasting and braking. Under the conditions of the train
running time, running distance and speed, we use the punctuality of running time, the accuracy
of the train stopping and energy consumption to be the goal of optimization. And then we use
the weighted average of these three optimization goal to be the overall optimization goal, and
build a multi-objective optimization train model. In solving the optimization problem, we use
particle swarm optimization to optimize the distance of running conditions under certain
operating conditions. The results of the simulation proved its effectiveness.
