Stackelberg game for two-level supply chain with price markdown option

Vendor–retailer collaboration has an important role in supply chain management. Although vendor–retailer collaboration results in better supply chain profit, collaboration is difficult to realize. This is because most vendors and retailers try to optimize their own profit. This paper applies the Stackelberg game with
stochastic demand for the vendor–retailer system. The vendor as a leader determines the product price,
and the retailer decides order quantity and frequency of price markdown. This study develops example
and sensitivity analyses to illustrate the theory. Results show that the price markdown option has a better total supply chain profit than without a price markdown policy, and the vendor receives more benefit. For different demand variances, the retailer profit is more sensitive than the vendor profit.
