Embodiment Construction
[0033] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.
[0034] The present invention provides a multi-level configuration method for ship main engine spare parts based on fault correlation feature model, such as figure 1 As shown, it includes three levels.
[0035] The first level is the main spare parts judgment layer, including data perception and preprocessing, the establishment of the host state parameter database, the confirmation of the main abnormal component and the life prediction.
[0036] The second level is the j...

The invention discloses a marine main engine onboard spare part multi-level configuration method based on a fault correlation model, and the method comprises the following steps: obtaining dynamic perception information and static historical data information which represent the state of a marine main engine, and then constructing a main engine state parameter database; performing abnormity judgment on the data information representing the host state, obtaining a component corresponding to abnormal state data, realizing life prediction of the component corresponding to the abnormal state data based on a life prediction model, and performing spare part evaluation judgment; analyzing the feasibility of the associated spare parts through the association state matrix, the fault association model and the associated spare part life prediction model; and performing on-ship configuration judgment on the main-associated spare parts by taking the maintenance cost as a constraint, and obtaining a spare part list. Compared with the prior art, fault correlation factors are considered in ship main engine onboard spare part prediction, the guarantee rate of the ship main engine spare parts can be effectively improved, and the investment expenditure of the spare parts can be reduced while the navigation risk is reduced.
Description
technical field [0001] The invention relates to the field of ship main engine spare parts configuration, in particular to a multi-level configuration method for ship main engine spare parts on board based on a fault correlation model. Background technique [0002] During the ship's voyage, the guarantee of the spare parts of the ship's main engine is a necessary guarantee for the normal operation of the main engine. Premature or too many spare parts will cause the company's funds to be occupied for a long time, and will increase the cost of navigation. However, insufficient spare parts configuration may make the navigation risky, resulting in the failure to complete the navigation mission smoothly and on time. Therefore, a reasonable on-board spare parts configuration of the ship's main engine is an important guarantee for the smooth completion of navigation tasks. [0003] Zhang Xinhui et al. optimized the joint strategy of maintenance and spare parts ordering based on th...
