4. The university Bookstore at Tech is considering several expansion projects, including developing a store Web site for online retail and catalog purchases, buying an off-campus warehouse and its subsequent expansion, developing a clothing and gift department specializing in university logo apparel, opening a computer department carrying both hardware and software products, and creating a banking pavilion of three automated teller machines outside the store. Some of the projects will be developed over a two-year period and some over a three-year period, as funds permit. The costs per year and the projected net present value of returns for a 5 year period for each of the projects are shown on the following table. Project NPV Return Web site $120 Warehouse 85 Clothing Dept. 105 Computer Dept. 140 ATMs Available fund each year Project Costs/year($1,000s) 1 2 3 $5$ $40 $25 45 35 20 60 25 50 35 30 70 30 30 $150 $110 $60 In addition, the store does not have enough space available to create both a computer department and a clothing department. The Bookstore director wants to know which project to select to maximize return. Note: 1. If university bookstore had specified that either the computer department (x4) or the clothing department (x3) must be built but not both. 2. If the university bookstore had specified that exactly two of the five projects must be undertaken. Formulate linear programming model for this problem. Don't need to solve this one. 4.
