Consider the Wyndor Class example we showed in the class. Now the market fluctuates and

he situations of all three plants change, a new set of parameters are provided as follows:

$(20$ pts$)$ Use the robust optimization method to solve this problem. What is the resulting

optimal solution and how much is the total profit?

$(10$ pts$)$ Wyndor's m$$nager requires that the solution $x_1,x_2$ should be integer. In this case,

what is the optimal solution and how much is the profit?
