Ship lock maintenance plan making method based on system availability

The invention discloses a ship lock maintenance plan making method based on system availability, and belongs to the technical field of water transport engineering. The ship lock maintenance plan making method comprises the following steps: S1, establishing a ship lock life cycle information basic database; S2, analyzing the structural reliability of the ship lock system; S3, constructing a ship lock system reliability model by utilizing the basic data; S4, estimating the availability of the ship lock system in the research period; and S5, generating a maintenance plan based on the maximum system availability. The method comprehensively considers the influence of the maintenance activity on the availability and production operation of the ship lock system, can be used for dynamically analyzing and managing the ship lock maintenance plan, optimizes the medium maintenance and heavy maintenance plan in the use period of the ship lock, is helpful for forming scientific and effective ship lock maintenance measures,
