Onboard spare part optimization algorithm based on marginal effect

Abstract

The invention provides an onboard spare part optimization algorithm based on a marginal effect. The method comprises the steps of collecting the on-board spare part consumption standard and turnover standard data, calculating the on-board spare part failure rate, calculating the probability distribution of the demands of the on-board spare part, calculating the lack number of the on-board spare parts, ect. According to the onboard spare part optimization algorithm based on the marginal effect, the efficiency cost calculation and evaluation can be carried out on an existing scheme, the onboardspare part inventory can be reasonably assembled, and the optimal onboard spare part inventory scheme under different expenses is obtained, and the contradiction of expenditure shortage and spare partshortage can be effectively solved. Specifically, the onboard spare part inventory scheme obtained by utilizing the method can play an important role in the following aspects that the equipment shutdown time caused by shortage of onboard spare parts is reduced, and the availability of the equipment is effectively improved; the investment risks of on-board spare parts are reduced, the backlog of the spare parts is reduced, and the utilization rate of the spare parts is effectively increased, and a theoretical basis is provided for the optimal inventory setting of the on-board spare parts.

Description

technical field [0001] The invention relates to the technical field of equipment maintenance support and spare parts inventory optimization, in particular to a marginal effect-based on-board spare parts optimization algorithm used for ship equipment maintenance support and on-board spare parts inventory optimization. Background technique [0002] Reasonably determining the inventory of spare parts on board is the main means to improve the use effect of spare parts and avoid waste, and it is also an effective way to ensure the working ability of equipment and improve the availability of equipment. In the case of ship equipment going to sea to perform missions, the inventory of spare parts on board plays a huge role. It is an important part of the ship's equipment to successfully complete the mission and is directly related to the quality and efficiency of mission completion. However, the current actual situation is that based on the past The on-board spare parts inventory pla...

In the case of ship equipment going to sea to perform missions, the inventory of spare parts on board plays a huge role. It is an important part of the ship's equipment to successfully complete the mission and is directly related to the quality and efficiency of mission completion. However, the current actual situation is that based on the past The on-board spare parts inventory plan based on the experience of performing missions, the cost of on-board spare parts is high and the efficiency is low, and there are many unreasonable situations in the inventory, such as high demand but low inventory, low demand and high inventory, which in turn leads to "tight funds and shortage of spare parts" The contradictions are becoming more and more prominent, and even the equipment is unsustainable
