An optimization method for spare parts allocation of ship equipment in the state of no maintenance

Abstract

The invention discloses a method for optimizing the configuration of spare parts of naval equipment in the state of no maintenance, including building a reliability calculation model during equipment storage and a reliability calculation model during equipment use; calculating the use reliability benefit value Δp of the equipment xk , to obtain the reliability benefit matrix of the equipment; obtain a set of reliability benefit values ​​corresponding to the spare part configuration plan in the reliability benefit matrix according to the initial spare parts configuration plan, select the maximum value of the reorganized reliability benefit value, and replace it with the The corresponding reliability benefit value when the number of spare parts is increased by one, and the corresponding spare part data is increased by one, and the spare part configuration scheme is updated to obtain the minimum service reliability of the equipment under the spare part scheme. The method of the technical solution of the present invention fully considers the spare parts requirements of the equipment in the storage and use stages, obtains the corresponding reliability benefit value, and at the same time solves the constraints on the spare parts configuration scheme, and can further obtain an effective optimal spare parts configuration scheme.

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
