A model of train optimal operation problem is established in according to the process dynamics equations, the fraction and brake capability, the railway resistance, and the speed limits. As the ramp resistance and the running resistance are introduced, the process described by Ordinary Differential Equations (ODEs) in the constrains are then transformed into Differential Algebraic Equations (DAEs), which makes the problem more difficult. In order to solve this problem, the state and control variables are parameterized in the time domain, converting the original control problem into a constrained nonlinear programming problem, which is finally solved by primal-dual predictor-corrector interior-point algorithm.
