A Comparative Research On Supply Chain Strategies Under Indefinite Delivery

For a long time, there exist three big uncertainties in supply, manufacture and demand of the supply chain operation and more attention has been paid on indeterminate manufacturing and demand of the effect on supply chain operation. However, with the recent social emergencies and natural disasters led to the upstream supply chain frequently interrupt, people begin to pay close attention to uncertainty in the process of supply. In the process of supply for manufacturers, supply’s output random and supply capacity uncertainty is the important reason of the uncertain quantities of delivery.JIT and VMI strategy are widely used in the process of supply chain the existing literature on the research of the uncertain number of delivery more concentrated in the independent JIT strategy is a just in time Procurement model. It is maximally eliminate waste, reduce inventory, to achieve zero inventory. But under the environment of supply chain, JIT is the pursuit of the buyer’s optimal strategy. The Vendor Managed Inventory (VMI) is the act of one’s own free will break the traditional inventory management model, reflects the integrated supply chain management ideas, to adapt to changes in the market demand is a new representative of the inventory management thought. decision-making, the joint optimal decision situations such as suppliers, vendors using JIT, VMI supply mode of the cost and profit analysis. These studies are limited in a separate study either the cost of supplier and seller under two kinds of supply mode, either delivery in determining the number of cases the comparison of two kinds of supply mode, and neglect in the case of uncertain delivery number two strategies of the contrast.According to this problem, this paper under the condition of uncertain delivery quantity, Introduced by the seller due to the insufficient number of supplier delivery established by the vendor of their punishment penalty cost, by comparing the suppliers and vendors adopt the JIT and VMI strategy cost under the situation, Through the establishment of cost model analysis and comparison for the supply chain delivery.Draw the following conclusion through the computer simulation data:When the retailer’s order quantity is half of the seller’s deliver ability, the JIT strategy’s total supply chain cost is the same as VMI strategy’s.When the retailer’s order quantity is less than a half of the seller’s deliver ability, the VMI strategy’s total supply chain cost is less than JIT strategy’s.When the retailer’s order quantity is more than a half of the seller’s deliver ability, the JIT strategy’s total supply chain cost is less than VMI strategy’s.This can provide reference to the supplier and the manufacturer in the supply chain, The two sides through combining with its own characteristics and the market’s overall planning, according to the different order of vendor’s, bargaining to each other, then can select a suit for benefit of both parties and make the total cost decreases supply strategy.
