Replenishment Strategy in VMI under Dynamic Demand
In the"supplier-electric power company"two-level supply chain system,some materials adopt the supplier management inventory strategy.Because of the uncertainty of supply caused by unqualified sampling,it brings a lot of difficulties to the dy-namic replenishment strategy of materials.In order to solve this problem,the replenishment cycle and safety stock setting were optimized by establishing an optimization model aiming at cycle cost function,and the replenishment strategy under dynamic un-certainty was obtained.The results show that the optimal safety inventory level decreases with the increase of unit holding cost and demand forecast lead time,and increases with the increase of unit shortage cost and lead time.The optimal order cycle in-creases with the increase of lead time and is the same as the lead time.The simulation studies how suppliers determine the or-der cycle and safety inventory to deal with the uncertainty of supply and demand,which has application reference value for enter-prises implementing the supplier managed inventory model.
