The daily production quota for the two products are 80 and 60 units, respectively. Each machine runs 8 hours a day. Overtime, though not desirable, may be used if necessary to meet production quota.
Formulate the above problem as a goal programming model.
(2 Marks)
(b): Formulate the following as an Integer Programming Problem:
We have landed in a treasure island full of three types of valuable stones: Emerald (E), Ruby (R) and Topaz (T). Each piece of E, R and T weighs 3, 2, 2 kilogram respectively and is known to have a value of 4 crore, 3 crore and 1 crore respectively. We have got a bag with us that can carry a maximum of 11 kg. Our problem is to decide on how many pieces of each type to carry, within the capacity of our bag, so as to maximize the total value carried. The stones cannot be broken.
