Consider the network described in the table below. Most Immediate Optimistic Likely Activity Predecessor(s) Time (days) Time (days) A none 5 8 B 7 Pessimistic Time (days) 17 13 none 10 A 3 5 7 D A 1 3 5 G B,D 4 6 8 3 E 3 B,D CE F 2. 7 What is the probability that the project can be completed in 19 days or less about 22% about 58% 78% about 42% Seven activities are candidates for crashing on a network. The activity details are in the table below. Normal Crash Normal Time (days) 8 Crash Time (time) 6 Cost Cost A 100 120 B none none A 8 7 120 180 5 5 4 80 100 . 4 3 120 150 D G 5 4 160 200 E B,D B,D CE 3 3 14 0 F 3 1 80 200 Mark the correct answer Reduce the project by 3 days. Below is the order of crashing for each day and the total added cost. day 1 = A, day 2 = A day 3 = G. The total added cost = $40 The duration of the critical path is the average duration of all paths in the project network. day 1 = A; day 2 - C; day 3 = D. The total added cost = $60 day 1 = A; day 2 = A; day 3 = D. The total added cost = $50
