Game for early order commitment discount in a two-level supply chain;

Optimal early order commitment discount in a supply chain with one supplier and multiple retailers

Quantity-based shipment consolidation and stock replenishment policy with lead time in vendor-managed inventory system;

The lead time is related to upstream supplier s service style, the paper analyses the impact on direct military supplier s lead time with two different order service policies, first come first serve (FCFS) and dominated policies, at the upstream suppliers.

Based on credibility theory,this paper studies how to evaluate the safety inventory of node enterprise given constant lead time and fuzzy lead time under fuzzy demand,analyzes the impact of supply uncertainty on safety inventory on fuzzy demand,and compares the correlative issues with stochastic demand.

Through the analysis of the theory and enterprise practice,the result shows:the correlation between order batch and lead time is positive;order lead time will change with batch chan- ging in the same direction;the changing lever of order lead time with changing of batch in a higher position is greater than the changing lever in a lower position batch.

Finally paper carries on the explanation through the value example to the models analysis\'s results, and further investigates the influence that the controllable order lead-time compression of the powerful retailer affects the optimal strategy of the powerful retailer.
