Research on Multi-Echelon Inventory Optimization for Fresh Products in Supply Chains

Abstract

Fresh products are perishable and fragile, which easily leads to higher inventory costs and requires reasonable planning of inventory management. Therefore, it is very important for fresh product supply chain systems to have multi-echelon inventory control. However, in past studies, few control models of the multi-echelon inventory considered the deterioration rate of perishable products as the variable factor. In this paper, on the basis of considering the perishable characteristics of fresh products, combining the deterioration rate with the inventory control model, a multi-echelon inventory control model for fresh products is designed and optimized, and the optimal solution from the whole supply chain is obtained through the optimal fitness function by genetic algorithm. Finally, Flexsim is used to simulate the two inventory strategies before and after optimization. After simulation comparison and analysis, it is verified that the optimized inventory control strategy has lower costs. The research results can help supply chain managers of fresh products to make inventory management decisions and save costs, which is of practical significance.

Towards a Digital Twin Warehouse through the Optimization of Internal Transport

“…The difficulties in terms of regularity of supply and the homogeneity of the formats in which this material is supplied make it necessary for certain types of companies to propose storage and logistics solutions that are adaptable to these new conditions. All this is accentuated when the stored material deteriorates easily, which requires particular inventory management [13] and a definition of the strategy during storage [14], including when these materials are used as packaging. Unlike raw materials, recycled materials are not always presented in a stackable or even homogeneous form.…”

The optimization of inventory control strategy in the three-echelon supply chain under palletized unit load-based logistics

“…Zhao [2] pointed out that pallets sharing can improve the efficiency of logistics distribution and reduce the input cost of pallets, Manjeet et al [3] designed a two-stage algorithm to optimize the goods palletizing scheme, Piao et al [4] studied the impact of palletized unit load-based logistics on Farmers' fruit and vegetable sales and distribution strategies; For inventory control, many scholars studied the inventory system under different scenarios and the optimization methods of inventory control. Sebatjane et al [5] studied the three-echelon inventory system composed of farmers, factories and retailers，Li et al [6] studied the platelet inventory model with short shelf life and uncertain demand, Wang et al [7] studied the fresh product inventory model with freshness and quantitative loss function, Zhang et al [8] designed the inventory control strategy optimization algorithm combining Flexsim simulation and genetic algorithm.…”
