Four buildings (B1, B2, B3 and B4) are to be constructed by four different contractors (C1, C2, C3 and C4). Each contractor has submitted the bid for the four buildings. The bid amount has been shown below. The problem is to determine which building is to awarded to each contractor, so as to keep the cost of construction of four building optimum.
