specific Embodiment approach

[0030] Optionally, as a specific implementation of the spare parts inventory optimization method provided in the embodiment of the present invention, the spare parts warehouse optimization model is:

[0031]

[0032] Among them, C j is the unit price of item j spare parts, s mj is the inventory of the spare parts of item j at the site, A is the availability of spare parts, A 0 is an indicator of availability.

[0033] Please also refer to figure 1 and figure 2 , figure 2 It is a schematic flowchart of a spare parts inventory optimization method provided in another embodiment of the present application. On the basis of the above embodiments, the marginal effect method is used to solve the spare parts inventory optimization model, including:

[0034] S201: Initialize the inventory of spare parts.

[0035] In this embodiment, the inventory of spare parts can be set to 0, that is, s mj =0.

[0036] S202: Calculate the marginal effect value of each spare part, and add...

Abstract

The invention provides a spare part inventory optimization method and device. The method is applied to the technical field of inventory control and logistics management. The method comprises the following steps: setting an equipment spare part system availability index; based on the availability index, establishing a spare part inventory optimization model by taking the spare part availability asa constraint condition and taking the minimum total guarantee cost of the spare part as an optimization target; and adopting the marginal effect method to solve the spare part inventory optimization model, and determining an optimal spare part inventory scheme. According to the spare part inventory optimization method and device provided by the invention, the spare part inventory optimization model is established based on the availability of the equipment spare part system, more scientific decision can be made for the optimal configuration of the equipment spare parts, the war readiness integrity of the equipment is improved, and a large amount of inventory cost can be saved.

Description

technical field [0001] The invention belongs to the technical field of inventory control and logistics management, and more specifically relates to a spare parts inventory optimization method and device. Background technique [0002] Equipment spare parts are the supporting materials for normal maintenance and overhaul of equipment, and are the material basis and important guarantee for equipment maintenance. They not only affect the life cycle cost of equipment, but also directly affect the integrity of equipment (such as availability, dispatch rate, and ability to perform tasks). rate) and its combat effectiveness. [0003] String repair can maximize the availability of equipment under the same conditions, but in the equipment structure, not all items can be chained. Horizontal transshipment can realize resource sharing between inventories at the same level, but it does not consider the average delay time of spare parts guarantee in the inventory system. Therefore, how t...
