the following questions. Note each of these questions are variations from the base model. As such, use the base model as the starting point to answer each question separately. Note also that each question 1 through 5 is independent and based off the original optimum solution. In other words, they are not continuations. Each question (1 through 5} represents independent changes to the original model. 1- Dave is not sure that the l'side" constraint of at least as much gasoline A as Gasoline B is necessary. What is this constraint costing the company? That is, how much more revenue could Jansen earn if this constraint were ignored? 2. Dave consults the chemical experts, and they suggest that Gasoline A could be produced with a "medium" level of TEL. The octane ratings for each feedstock with this medium level would be halfway between their low and high TEL octane ratings. Would this be a better option {what is the maximum revenue for this option)? 3. Because of regulations Jansen may have to increase Reid Vapor Pressure maximum value on each gasoline type (by the same amount). Conduct a sensitivity analysis to the base model by varying Max Reid Pressure requirement from 7 to as high as 15 (in increments of 1}. Determine the maximum Reid Vapor Pressure value ascertained and the associated revenue. Show a plot and data table of varying read pressure to the revenue and amount of gasoline (Total of A, B and C) produced. Lasty, what is the minimum value of revenue when varying Reid Vapor Pressure maximum value that results lowest revenue. 4. Dave believes that the minimum required octane rating for gasoline A is too low. He would like to know how much this minimum rating could be increased before there would be no feasible solution (still assuming that Gasoline A uses the low TEL level). What is the highest value that this minimum octane rating could be increased to before no feasible solution is ascertained? What is the associated revenue with this minimum octane value? 5. Dave suspects that only the relative prices matter in the optimal blending plan. Specically, he believes that if all unit prices of the gasoline types and all unit values of the feedstocks increase by the same percentage, then the optimal blending plan will remain the same. Is he correct? To test this show a plot and data table of resulting revenue and total gas produced contrasted to increasing unit prices of the gasoline types and all unit values of the feedstocks increase by the same percentage from 0% to 10%
