To estimate a failure causal device when an elevator fails more accurately than before.SOLUTION PART: A failure recovery support system includes: an operation data storage unit that stores elevator operation data; a maintenance history storage unit 220 that stores a maintenance history of the elevator; a failure status information acquisition unit 212 that acquires operation data of the elevator that issued error information; a similar failure history search unit 215 that searches the failure history similar to the elevator for which the failure status information acquisition unit has acquired the error information; and a probability correction processing unit 216 that corrects the failure occurrence probability of a failure causal device candidate searched by the similar failure history search unit on the basis of at least one of the operation data accumulated by the operation data storage unit and the maintenance history accumulated by the maintenance history storage unit. The probability correction processing unit 216 optimizes and notifies the failure history similar to the failure that has occurred with the probability corrected by the probability correction processing unit.SELECTED DRAWING: Figure 1

    【課題】昇降機が故障した際の故障原因機器の推定が、従来よりも精度よく行えるようにする。【解決部】昇降機の稼働データを蓄積する稼働データ蓄積部と、昇降機の保全履歴を蓄積する保全履歴蓄積部220と、エラー情報を発報した昇降機の稼働データを取得する故障状態情報取得部212と、故障状態情報取得部がエラー情報を取得した昇降機と類似した故障履歴を検索する類似故障履歴検索部215と、稼働データ蓄積部が蓄積した稼働データと、保全履歴蓄積部が蓄積した保全履歴との少なくともいずれか一方に基づいて、類似故障履歴検索部が検索した故障原因機器候補の故障発生確率を補正する確率補正処理部216とを備える。確率補正処理部216は、発生した故障に類似した故障履歴を、確率補正処理部が補正した確率で最適化して通知する。【選択図】図1
