The Uncertainty Of Demand Supply Chain Inventory Management Strategies

The supply chain is facing more and more complicated uncertainty under the circumstance of intensified global integration and the financial crisis, so the stock management is turning more important, which is one of the key factors to enhance competitiveness of supply chain.Firstly, this paper analyzed common stock-control theories and models. Furthermore, this paper studied the uncertainty of supply chain, analyzed the influence of sources of uncertainties on stock, and raised two strategies in details to decrease the uncertainty of supply chain, which is active elimination and passive response. Finally, this paper established a Mathematics model, calculated the hold cost, order cost and short-off cost based on the supply-chain system with one manufacturer, one distributor and N retailers. In the model, the total cost is the objective function and the security index is the decision variable. The model considered two situation, they are distributed strategy and centralized strategy, provided optimized solution method, and proved centralized strategy was more advantaged than distributed strategy on cost-saving.
