Order decision-making method for aviation equipment maintenance materials based on importance and inventory limit

Abstract

The invention relates to a decision-making method for ordering aviation equipment maintenance equipment based on importance and inventory limit, which includes the following steps: acquiring the influence degree of maintenance equipment on flight missions, maintenance equipment financing, maintenance equipment consumption and maintenance equipment unit price information, and establishing Importance evaluation model to obtain the importance A of maintenance equipment; establish an importance level formulation model according to the importance of maintenance equipment to obtain the importance level number of maintenance equipment; establish an inventory limit model; establish an order model and an order optimization model; When ordering, the sum of the maintenance equipment on hand and the ordered quantity is within the inventory limit calculated by the inventory limit model. The invention optimizes the standard of basic failure turnover from the perspective of equipment system, ensures that the equipment stored according to the lower limit of inventory can make the good rate of aviation material guarantee of a model reach the level of actual requirements, and improves the accuracy of ordering maintenance equipment.

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
