Study Questions for Scheduling Material CEE 590 Fall, 2007 1. Consider the activity-on-arc project network shown below, with activity (task) durations (in days) listed alongside each arc. 1 2 3 4 5 7 6 B A C D J E G F H I 6 5 3 10 15 6 3 10 12 8 (a) What is the Earliest Start time for task I? (b) What is the Latest Finish time for task E? (c) What is the Earliest Finish time for task J? (d) How many days of total float does task H have? (e) How many days of free float does task D have? Answer: Doing the forward and backward passes through the network, we find the following (earliest, latest) time values for the event nodes: 1: (0, 0) 2: (5, 5) 3. (8, 8) 4: (14, 17) 5: (20, 20) 6: (20, 20) 7: (28, 28) From these values, we can compute the answers to parts (a) through (e): (a) 20 (b) 20 (c) 15 (d) 20 – 14 – 3 = 3 (e) 14 – 0 – 10 = 4
