\f1. (Adapted from p. XX of Chase, Aquilano, and Robert (2002)). Many firms that have tried to enter the notebook computer market have failed. Suppose your firm believes that there is a significant demand in this market because existing products have not been designed correctly. They are too heavy, too large, or too small to have standard-size keyboards. Your intended computer will be small enough to carry inside a jacket pocket if need be. The ideal size will be no longer than 5 inches x 9 + inches x 1 inc with a folding keyboard. It should weigh no more than 15 ounces and have an LCD, a microdisk drive, and an Ethernet port. This should appeal to traveling business people, but it could have a much broader market, including students. It should be priced in the $175-$200 range. Then, the project is to design, develop, and produce a prototype of this small computer. In the rapidly changing computer industry, it is crucial to hitting the market with a product of this sort in less than a year. Therefore, the project team has been allowed for approximately eight months (35 weeks) to produce the prototype. 2. (Adapted from p. 95 of Chase, Aquilano, and Robert (2002)). A project has been defined to contain the following list of activities and their required times for completion: Activity Time (Days) Immediate Predecessors A B A A D 7 A E 6 B F 2 C. D G 7 E, F H D G, H a) Draw the critical path diagram. b) Show the early start and early finish times. c) Show the critical path. d) What would happen if activity F was revised to take four days instead of two?4. (Adapted from pp. 95-96 of Chase, Aquilano, and Robert (2002)). A project has been defined to contain the following activities, along with their time estimates for completion.
