Abstract: It considers a two-stage supply chain with one warehouse and many retailers. The mathematical model is defined as the warehouse with two different channels and the different priorities of retailers. Then a modified genetic algorithm is designed and a two-stage inventory allocation mechanism is proposed to solve the inventory allocation problem with the aim of minimizing the total cost of the supply chain. Application data are obtained to validate the model, the result shows that the proposed mechanism is better than the modified First Come First Service mechanism（FCFS） and the GAP between the solution of GA with the proposed mechanism and optimal solution of Cplex is less than 10%. The numerical experiment indicates that the proposed mechanism can solve the inventory allocation and the algorithm can determine the parameters of the inventory strategy effectively.
