Abstract: All of the effects resulting from the interaction between the fixed railway infrastructure and its mobile counterpart are embodied on the time dimension, but it’s hard to express the dynamic characteristics of the train’s acceleration/deceleration and the approximate constant speed with the precise data. Based on these, according to the topology of the station tracks and the passenger demand of high speed railway, combined with the dynamic characteristics of the train run, this paper puts forward the basic research thinking for the application of the Fuzzy Timing High-level Petri Nets (FTHNs)-Conflict Graph double model to research on the computation & evaluation of the high speed railway station. It defines the train service-demand intention set (t @ s-TSDIS) in a period, aiming at the minimization of the station tracks’ occupation time for the completion of the defined t @ s-TSDIS, and synthetically applies the FTHNs, Max Plus, improved simulated annealing for the optimization of the station tracks’ occupation order.
