Integrated Joint Replenishment and Distribution Model Using Hybrid Differential Evolution Algorithm

2012 
Considering joint replenishment and distribution decision when stock out is allowed,a model integrating multi-buyer joint replenishment and distribution with stochastic demand is analyzed.A hybrid differential evolution(HDE) algorithm is designed to solve the proposed model.An example shows the performance of the HDE is more stable and efficient compared with genetic algorithm and typical differential evolution algorithm.In addition,a two-stage model with replenishment and delivery uncoordinated is designed.The numerical experiments illustrate the fact that the replenishment cost is higher,distribution cost is lower and total cost is lower under supply chain collaboration.Finally,the sensitivity analysis on relevant parameters is addressed and the results show the influence of variations in demand rate and inventory holding cost on the total cost is far greater than that of variations in minor ordering cost on the total cost.
