Aviation equipment maintenance equipment ordering decision-making method based on importance and inventory limit

Abstract

The invention relates to an aviation equipment maintenance equipment ordering decision-making method based on importance and inventory limit, and the method comprises the following steps: obtaining the impact degree of maintenance equipment on a flight mission, the preparation condition of the maintenance equipment, the consumption of the maintenance equipment and the unit price information of themaintenance equipment, building an importance evaluation model to acquire the importance A of the maintenance equipment; establishing an importance grade making model according to the importance of the maintenance equipment to obtain the importance grade number of the maintenance equipment; establishing an inventory limit model; establishing an ordering model and an ordering optimization model; and carrying out ordering according to the ordering model or the ordering optimization model. During ordering, the sum of the existing number of the maintenance equipment and the ordering number is within the inventory limit calculated by the inventory limit model. The basic fault turnover standard is optimized from the perspective of an equipment system, it is ensured that good guarantee rate of navigation materials of one aircraft type can reach the level of actual requirements according to the equipment stored according to the inventory lower limit, and ordering accuracy of the maintenance equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of aviation equipment maintenance, and relates to an order decision-making method for aviation equipment maintenance equipment based on importance and inventory quota. Background technique [0002] It is necessary to determine which equipment is important in the drafting of aviation equipment procurement and supply standards, the determination of carrying equipment for carrier-based aircraft escort, and the formulation of aviation equipment maintenance and support plans. Bring more, not only order but also order more when ordering. At present, the importance of relevant aviation equipment has not been formulated in China. The degree of importance is one of the important bases for the order decision support system to realize intelligent decision-making, and another important base is the inventory limit standard. At present, the country is comprehensively promoting the formulation of aviation equipment maint...

AI Technical Summary

Problems solved by technology

[0004] In summary, the existing literature on the distribution of equipment demand is chaotic, even contradictory, and only hypotheses do not provide scientific basis

In addition, the existing research on equipment ordering has not comprehensively considered the importance, importance level and inventory limit of equipment, which is not conducive to the decision-making of equipment ordering
