To provide a maintenance support system capable of providing information for carrying out replacement/repair, etc. at more appropriate time for each piece of equipment before performing maintenance on a maintenance target, a maintenance support method, and a program.SOLUTION: An equipment maintenance decision support system 1 includes: a load distribution estimation unit 102 that estimates at least one of a load placed on a maintenance target depending on time and a load placed on the equipment that constitutes the maintenance target depending on the time; a failure probability estimation unit 103 that estimates a failure probability, which is a probability that a failure will occur in the equipment depending on time, on the basis of the estimated load; and a risk/cost calculation unit 104 that estimates a risk when a problem occurs in operation of the maintenance target on the basis of, the predicted probability of failure occurrence and cost required for maintenance of the maintenance target on the basis of, the probability of failure occurrence.SELECTED DRAWING: Figure 1 【課題】保守対象の保守を行う際に、それぞれの設備毎に、より適切なタイミングで取替・補修等を行うための情報を得ることができる保守支援装置、保守支援方法およびプログラムを提供する。【解決手段】時間に応じて保守対象にかかる負荷および時間に応じて当該保守対象を構成する設備にかかる負荷の少なくとも一方を推定する負荷分布推定部１０２と、推定された負荷を基に、時間に応じて前記設備に故障が発生する確率である故障発生確率を予測する故障確率推定部１０３と、予測された故障発生確率を基に、保守対象の運用に支障が生じたときのリスクを推定するとともに、故障発生確率を基に、保守対象の保守に要するコストを推定するリスク・コスト算出部１０４と、を備える設備保全意思決定支援システム１。【選択図】図１
