Question:
A petroleum refinery in Dubai wants to expand its refinery and stock-yard for the expected surge in the oil prices in the coming years. The company has four distinct activities in its strategic plan—plant expansion, stockyard improvement, adopting modern technology and research and development. Each of the different activities has a cost and an expected NPV. The following table lists the costs, available capital, and NPV of each activity required to execute each of the options in millions of dirhams.
The company wants to maximize it’s net present value considering its budgetary constraints.
a. Formulate an integer programming model for this problem.
b. Solve this model by using the computer.

NPV stands for \"Net Present Value,\" which is a financial concept used to determine the value of an investment or project. It measures the difference between the present value of cash inflows and the present value of cash outflows over a given period of time, using a specific discount rate. To calculate the NPV of an investment, you need to first estimate the cash inflows and outflows associated with the investment, and then discount them back to their present values using a discount rate. The discount rate represents the cost of capital or the expected rate of return required by investors. The formula for calculating NPV is: NPV = sum of (cash inflows / (1 + discount rate)^t) - sum of (cash outflows / (1 + discount rate)^t) Where: Cash inflows: the expected cash received from the investment Cash outflows: the expected cash paid out for the investment Discount rate: the required rate of return or the cost of capital t: the time period in which the cash flow occurs If the NPV is positive, it means that the investment is expected to generate a return higher than the required rate of return or the cost of capital, and it may be considered a good investment. If the NPV is negative, it means that the investment is not expected to generate a return higher than the required rate of return or the cost of capital, and it may be considered a bad investment.
