Integer Programming

Roblem 11-19: A real estate developer is considering three possible projects: a small apartment complex, a small shopping center, and a mini-warehouse. Each of these requires different funding over the next two years, and the net present value of the investments also varies. The following table provides the required investment amounts (in $1,000s) and the net present value (NPV) of each (also expressed in $1,000s):

Investment
NPV Year 1 Year 2
Apartment 18 40 30
Shopping Center 15 30 20
Mini-warehouse 14 20 20

The company has $80,000 to invest in year 1 and $50,000 to invest in year 2.

(a) Develop an integer programming model to maximize the NPV in this situation.
(b) Solve the problem in part (a) using computer software. Which of the three projects would be undertaken if NPV is maximized? How much money would be used each year?

Hint(use 0/1 integer).

Solution Summary

Develops an integer programming model to maximize NPV for a real estate developer. Excel Solver is used to calculate the values.
