FACILITY MAINTENANCE SUPPORT SYSTEM AND FACILITY MAINTENANCE SUPPORT METHOD

To appropriately support maintenance planning even in the case of a small amount of stored failure history information about sections of facilities.SOLUTION: A facility maintenance support system 1S supporting maintenance of facilities including sections comprises a facility information processing unit which constructs respective lifetime distributions of facilities on the basis of identification information of the facilities and failure times at which failure occurred in the sections of the facilities in failure history information in which the identification information of the facilities, identification information of the sections, and the failure times are stored in association with each other. The facility maintenance support system 1S comprises: a section information processing unit which constructs respective lifetime distributions of the sections of each of the facilities on the basis of the identification information of the facilities, the identification information of the sections, and the failure times in the failure history information; and a failure probability and weight calculation unit which calculates a failure probability of each of the facilities on the basis of the lifetime distribution of each facility and calculates a failure probability of each section of each facility on the basis of the lifetime distribution of each section of each facility.SELECTED DRAWING: Figure 1 【課題】設備の部位の故障履歴情報の蓄積が少ない場合であっても、保全計画作成支援を適切に行う。【解決手段】部位を有する設備の保全を支援する設備保全支援システム１Ｓは、設備の識別情報と部位の識別情報と設備の部位で故障が発生した故障時刻を対応付けて蓄積した故障履歴情報の設備の識別情報と故障時刻に基づいて、設備ごとの寿命分布を構築する設備情報処理部を備える。また設備保全支援システム１Ｓは、故障履歴情報の設備の識別情報と部位の識別情報と故障時刻に基づいて、各設備の部位ごとの寿命分布を構築する部位情報処理部と、設備ごとの寿命分布に基づいて各設備の故障確率を算出し、各設備の部位ごとの寿命分布に基づいて各設備の部位ごとの故障確率を算出する故障確率・重み演算部とを備える。【選択図】 図１
