My presentation was on case study 4.1 Blending Aviation Gasoline at Jansen Gas. I used a blending model that shows the optimal blending plan of four feedstocks producing three types of gas and maximizes total revenue. I altered the original by removing the constraint of Gas A >= Gas B and added a calculation of the difference in total revenues. A second altered model adds the Octane (medium TEL) to the feedstocks and calculates the difference in total revenue. A third altered model adds and altered max Reid level and max Reid level change input and then I ran a one-way analysis to show that there are no feasible solutions if each gas type required a reduction in the max Reid pressure. I did a model with similar changes but to the min octane ratings that showed that if Gas A was produced at a low TEL level the min octane rating could only increase to 91. Finally, the last model alters the value per gallon of feedstocks and price per gallon of the gas types then I ran a one-way analysis to prove that if all unit prices of the gas types and all unit values of the feedstocks increase by the same percentage, then the optimal blending plan remains the same.
