Given the activities of a project; their optimistic (t.), most likely (t_) and pessimistic (t) time estimates; and their immediate predecessors shown below: 1. When is the earliest project completion? 2. Which activities are critical (should not be delayed]? 3. Which activities are noncritical (can be delayed)? 4. How long can each of the activities be delayed without delaying the whole project (maxmum slack)? Immediate Activity Times, months Maximum Slack, Activities Predecessors t. months 1 4 7 13 16 2 C.

A project P consists of 9 activities as shown below: Activity Predecessor(s) Duration (days) Cost ($) A 1 100 B A 2000 B 1 300 B 200 E 200 C, E 4 400 G 2 1600 G 1000 C, E 4 1600 2.

Perform the CPM (critical path method) and give the complete activity schedule table, the project completion time and the critical path.

Given the following activity network: Three nodes - A1, A2, A3; two paths - A1, A2 and A1, A3. Activity A1 takes 5 weeks, A2 takes 7 weeks, and A3 takes 4 weeks with a 50% probability and 10 weeks with a 50% probability. What is the project completion time under the worst-case scenario, that is, A3 is late and takes 10 weeks? A. 15 B. 10 C. 12 D. 9
