An Inventory Control Method Based on Optimum Replenishment Period of Spare Parts

Abstract

The present invention provides an inventory control method based on the optimal replenishment period of spare parts, the purpose of which is to reduce the inventory cost of spare parts in an enterprise as the core, and propose a complete inventory control method based on the optimal replenishment of spare parts by analyzing the influence of the replenishment cycle of spare parts on the inventory level. Cycle inventory control model to optimize enterprise spare parts inventory. Judging the optimal replenishment times of spare parts and the safety stock of spare parts storage in a replenishment cycle based on the historical demand characteristics of spare parts and the cost of spare parts procurement and storage, combined with the demand forecast value of spare parts, to determine the time and date of replenishment of spare parts Replenishment batches.

Description

technical field [0001] The invention belongs to the field of warehouse management, and in particular relates to an inventory control method based on the optimal replenishment cycle of spare parts. Background technique [0002] The common methods of spare parts inventory control mainly include inventory control based on spare parts demand forecast, inventory control based on spare parts replenishment cycle, inventory control based on spare parts shortage and loss, etc. Cui Nanfang et al. conducted research from the perspective of parts life function, and gave a high-value slow-moving spare parts inventory control model based on parts life function. Koopman, Kimball studied the corresponding inventory control strategy when the demand rate is a linear function. Ritchie solves the problem that the demand rate fitting function is complex and difficult to solve by using a simple straight line segment fitting solution method. At the same time, Ritchie also studies the inventory co...
