Anno Accesokmark Spencer Enterprises must choose among a series of new investment alternatives. The potential investment alternatives, the not present value of the future stream of returns the capital requirements, and the available capital tunds over the next three years are summarized as follows: Net Present Value (5) Capital Requirements (8) Alternative Year 1 Year 2 Year 3 4,000 3,000 1,000 4,000 0.000 2.500 3,500 3,500 Limited warehouse expansion Extensive warehouse expansion Test market new product Advertising campaign 10,500 6,000 4,000 5.000 4,000 2,000 1,500 1,000 Basic research 8,000 5,000 1,000 4.000 Purchase now equipment 3,000 1.000 500 000 Capital funds available 10,500 7.000 8.750 a. Develop and solve an Integer programming model for maximizing the net present value n. Assume that only one of the warehouse expansion projects can be implemented. Modify your model of part (a). Suppose that if test marketing of the new product is carried out the advertising campaign also must be conducted. Modily your formulation of part (b) to reflect this new ilian
