To provide a method by which a train diagram incorporating countermeasures for a train delay is generated using an analysis result of the delay.SOLUTION: A diagram preparation device 1 selects an object arrival/departure event from arrival/departure events based on an evaluation value per arrival/departure event. The diagram preparation device 1 transmits change time of arrival/departure related with an object arrival/departure event in a graph network corresponding to a train diagram 10 to another arrival/departure event and tries a change of the train diagram 10 by changing the arrival/departure time of the other arrival/departure event. In this trial, based on whether or not a combination of arrival/departure events related with the processes of the transmission affects the delay affected group, an extent of a change of arrival/departure time for the arrival/departure events related with this combination is changed and tried. The diagram preparation device 1 determines the success or failure of the trial and determines the change of the tried train diagram if the trial is determined as successful.SELECTED DRAWING: Figure 1

    【課題】列車遅延の分析結果を用いて遅延対策を実施した列車ダイヤを作成する技術を提供すること。【解決手段】ダイヤ作成装置1は、着発事象毎の評価値に基づいて、着発事象のうちから対象着発事象を選択する。ダイヤ作成装置1は、列車ダイヤ10に対応するグラフネットワークにおいて対象着発事象に係る着発時刻の変更時分を他の着発事象へ伝搬させて当該他の着発事象の着発時刻を変更することで列車ダイヤ10の変更を試行する。この試行の際に、当該伝搬の過程で辿る関連付けに係る着発事象同士の組み合わせが遅延波及組か否かに基づいて、当該組み合わせに係る着発事象の着発時刻の変更の程度を変えて試行する。ダイヤ作成装置1は、試行の成否を判定し、成功と判定した場合に、試行した列車ダイヤの変更を確定する。【選択図】図1
