Mixed Transshipments Problem Of Inventory Distribution Systems Of Company D

Inventory management is an important part of enterprise logistics management.Whether the reasonable control of inventory level directly determines the availability of goods and the inventory cost of enterprises.In the case of uncertain demand,the volatility of demand greatly increases the difficulty of enterprise inventory control.In order to improve customer demand satisfaction rate without increasing inventory levels,inventory transfer has become an effective inventory management method.This paper manages distributed inventory through a mixed-allocation inventory strategy,mainly conducting the following research.(1)This paper establishes a preventive transfer model under distributed inventory.Taking the distributed inventory system consisting of regional distribution center and front warehouse as the research object,and the regional distribution center as the coordination center of distributed inventory system,the current situation of preventive allocation under distributed inventory is studied,according to preventive allocation.Implement process and preventive transfer rules and establish a preventive transfer model.(2)On the basis of preventive allocation,consider multi-cycle and transfer lead time,introduce emergency transfer mode,and propose a mixed transfer strategy.Based on the premise that the customer is willing to wait,the safety stock is taken as the variable to be solved,and the mixed allocation model under distributed inventory is established.In the mixed allocation model,the regional distribution center serves as the coordination center to control the replenishment and transfer process of the entire inventory system.This paper introduces the allocation rules of preventive allocation,emergency allocation and mixed allocation strategy,and introduces the actual demand data,and uses the genetic algorithm to solve the mixed allocation model.(3)This paper introduces stochastic demand and simulates the preventive transfer model and the mixed transfer model.From the out-of-stock level,inventory level,average inventory system cost,and service level,the two methods are compared and analyzed,which verifies the feasibility and superiority of the mixed allocation strategy under stochastic demand.The key factors affecting the allocation decision under the mixed allocation strategy are briefly analyzed.This article includes Figure 17,Figure 7,and Reference 54.
