Part of the rocket used in F-4 aircraft at Eskiehir Supply and Maintenance Center is produced on
Question:
Part of the rocket used in F-4 aircraft at Eskişehir Supply and Maintenance Center is produced on 3 different types (A, B, C) machines, each of which produces different speeds and quality. The amount of machines that they can produce per hour, their degree of confidence and the cost of their one-hour operation are given in the table above. At least 2500 pieces must be produced every day in an 8-hour shift. Currently, there are 10 of the A type machine, 14 of the B type machine and 20 of the C type machine in the supply center. The error cost of each defective part is 10 000 currencies.
Since it is intended to minimize the cost, install the model required to determine how many of each machine will be operated in one day. (A 90% confidence rating shows that 10 out of 100 pieces produced are defective.)
a) Write down what the decision variables in your model show.
b) Explain your constraints in your model.
