Spare part configuration optimization method for naval vessel equipment under no-maintenance state

Abstract

The invention discloses a spare part configuration optimization method for naval vessel equipment under a no-maintenance state. The method comprises the following steps that: building an equipment storage period reliability calculation model and an equipment user period reliability calculation model; calculating the use reliability benefit value [Delta]pxk of the equipment, and obtaining the reliability benefit matrix of the equipment; and according to an initial spare part configuration scheme, obtaining one group of reliability benefit values corresponding to the spare part configuration scheme in the reliability benefit matrix, selecting a maximum value in a reorganized reliability benefit value, replacing the maximum value with the corresponding reliability benefit value when the number of spare parts is increased for one, meanwhile, increasing the corresponding spare part data for one, and updating a spare part configuration scheme so as to obtain the minimum use reliability of the equipment under the spare part scheme. By use of the method of the technical scheme, the spare part requirements of the equipment in storage and use stages are fully considered, the corresponding reliability benefit value is obtained, meanwhile, the spare part configuration scheme is subjected to solving constraining, and an effective optimal spare part configuration scheme can be further obtained.

Description

technical field [0001] The invention belongs to the field of ship equipment reliability and spare parts evaluation, and in particular relates to a spare part allocation optimization method for ship equipment in a non-maintenance state. Background technique [0002] A ship is a multi-functional independent combat unit integrating air, surface and underwater, which contains a variety of equipment components. In addition to frequently used equipment, there are also equipment with extremely short use time and long non-working time, which can also be called extremely low duty cycle equipment. For the extremely low duty cycle equipment placed on the ship after commissioning, compared with the packaged and stored equipment, the environment of the equipment on the ship when it is not working can be regarded as a special storage environment. The state is called the storage state, and the storage mentioned in this application document refers to the non-working state of the ship's equ...

Problems solved by technology

(2) Fault manifestations are different

At present, the formulation method of formation spare parts plan during missions is mainly determined according to the length of equipment working time, less consideration is given to the consumption of spare parts caused by long-term storage failure of equipment
