Tanura Co. is building a refinery to produce four products:
diesel, gasoline, lubricants, and jet fuel. The minimum demand (in
bbl/day) for each of these products is 14.000, 30.000, 10.000, and
8.000, respectively. Oman and Dubai are under contract to ship
crude to Tanura Co. Because of the production quotas, the new
refinery can receive at least 40% of its crude from Oman and the
remaining amount from Dubai. The specifications of the two crude
oils lead to different product mixes: One barrel of Oman crude
yields 0.2 bbl of diesel, 0.25 bbl of gasoline, 0.1 bbl of
lubricant, and 0.15 bbl of jet fuel. The corresponding yields from
Dubai crude are 0.1, 0.6, 0.15, and 0.1, respectively.
a. Formulate an LP that solves for the minimum capacity of the
refinery (in bbl/day) of Tanura Co. b. Solve the problem using
computer (show the computer output). c. What is the optimal
solution and what is the optimal value of the objective function?
d. Which constraints are binding? e. What will happen if the demand
of the diesel is reduced by 1,000 bbl/day? f. What will happen if
the demand of the gasoline is increased by 1,000 bbl/day?

Petro Refinery, Inc., located in Houston, TX, has separate
divisions for “Unleaded Gasoline” and “Jet Fuel”.
The variable costs are as follows:
■ Unleaded Gasoline division: $1.75
per gallon of unleaded gasoline
■ Jet Fuel division: $1.95 per gallon
jet fuel
Assume that there is no loss in processing unleaded gasoline
into jet fuel. Unleaded Gasoline can be sold at $2.25 per gallon.
Jet Fuel can be sold at $3.95 per gallon.

Ko-Ka-Ku Limited produces three main products from a joint
manufacturing process. Fuel oil, gasoline, Kerosene and Crude-I are
the products emerging from the joint manufacturing process. Crude-I
is aby-product and is sold at split-off, while the joint products
fuel oil, gasoline and kerosene need to be processed further.
