Chapter 10 Problem 9 9 A construction project is broken down into the following 10 activities: IMMEDIATE PREDECESSO TIME CTIVITY R (WEEKS) 1 4 2 1 2 3 1 4 4 1 3 5 2, 3 5 6 3 6 7 4 2 8 5 3 9 6, 7 5 10 8, 9 7 a. Draw the network diagram. b. Find the critical path. c. If activities 1 and 10 cannot be shortened, but activities 2 through 9 can be shortened to a minimum of one week each at a cost of $10,000 per week, which activities would you shorten to cut the project by four weeks? Chapter 10 Problem 10 Here is a CPM network with activity times in weeks: B(5) A(7) C(6) G(3) E(4) D(6) F(8) a. Determine the critical path. b. How many weeks will the project take to complete? c. Suppose F could be shortened by two weeks and B by one week. How would this affect the completion date?
