PROBLEM TO BE SOLVED: To create an operation curve aiming for energy saving by taking into consideration regenerative restriction in actual travel of a train.SOLUTION: An operation curve creation device of this invention includes an extraction unit and a creation unit. The extraction unit acquires travel data indicating a travel state of a train and extracts regenerative probability expressing feasibility of regenerative energy by regenerative braking of the train travelling in a prescribed section on the basis of the travel data. The creation unit calculates as transition cost a total of consumption energy of the train when state transition is carried out from the travel state to the next possible travel state the train may take and the regenerative energy reflecting the regenerative probability regarding each discretization travel state the train may take in the prescribed section according to the probability dynamic programming and creates an operation curve of the train in which accumulation of the transition cost is minimum when the train travels in the prescribed section by state transition between the travel states.SELECTED DRAWING: Figure 1
【課題】列車の実走行での回生絞り込みを考慮して省エネルギー化を図った運転曲線を作成する。【解決手段】実施形態の運転曲線作成装置は、抽出部と、作成部と、を備える。抽出部は、列車の走行状態を示す走行データを取得し、当該走行データに基づいて、所定区間を走行する列車の回生ブレーキによる回生エネルギーの発生し易さを表す回生確率を抽出する。作成部は、確率動的計画法に従って、所定区間において列車がとり得る離散化された各走行状態について、当該走行状態から次にとり得る走行状態に状態遷移した場合の列車の消費エネルギーと回生確率を反映させた回生エネルギーとの和を遷移コストとして算出し、走行状態間を状態遷移して列車が所定区間を走行した場合の遷移コストの累積が最小となる列車の運転曲線を作成する。【選択図】図1
