讲座摘要
     We study the case of a retailer who sources from two strategic suppliers subject to independent or correlated disruptions and sets the retail price after delivery. We model this problem as a Stackelberg-Nash game with the suppliers as leaders and the retailer as a follower, and obtain explicitly the equilibrium of the game. We show that the total order quantity in equilibrium does not exceed the abundant supply, defined as a threshold above which extra units will be salvaged. We study cases in which the retailer orders from one perfectly reliable supplier and one unreliable supplier, and two correlated unreliable suppliers. In the latter case, the suppliers chosen are based on combining consideration of wholesale prices and reliabilities. We show that increasing reliability may hurt the suppliers when competition level is high. For two unreliable suppliers, it is consistent with the literature that at the equilibrium, the retailer's profit increases in the supplier disruptions correlation, but the suppliers' profits may increase in that correlation. We also show that the random disruption assumption is not a particular case of the random capacity assumption.
