Abstract: This paper studies aquarium selling tickets to the tourists when speculators existing in the market. The aquarium sets a price and discount before demand uncertainty is resolved, and since the tourists are heterogeneous, speculators may enter the market purely with the intention of resale, which can be profitable if demand turns out to be high. Through the analysis of the model, we obtain the different discounts under the different situations. Research shows that the total revenue of supply chain in the centralized decision-making is greater than the revenue in independent decision-making when tourists follow uniform distribution. The maximum revenue of supply chain and both parties get their maximum revenue can be realized by coordinating the discount level. Finally, the related conclusions are illustrated by an example
