Critical Path Analysis and Algorithms

This video tutorial introduces the critical path algorithm, focusing on version one. It explains the steps to create a priority list by identifying critical paths in a task diagram. Through an example, the video demonstrates the trial-and-error process of finding the longest path and updating the priority list. The tutorial concludes with a brief introduction to version two, which uses the backflow algorithm to simplify the process.

What is the primary purpose of the Critical Path Algorithm?

• To create a priority list based on task importance

• To find the shortest path in a network

• To allocate resources efficiently

• To determine the minimum completion time for a schedule

Which step involves removing a task from the diagraph in Version One of the Critical Path Algorithm?

• Step 3

• Step 4

• Step 2

• Step 1

In the example, what is the total time for the critical path starting at Task 1 and going through Task 4 and Task 7?

• 15 hours

• 19 hours

• 17 hours

• 23 hours

What is the total time for the path from Task 2 to Task 5 to Task 8?

• 17 hours

• 19 hours

• 23 hours

• 15 hours

Which task is added to the priority list after Task 1 is eliminated?

• Task 4

• Task 5

• Task 3

• Task 2

What is the total time for the critical path starting at Task 6 and going to Task 8?

• 7 hours

• 14 hours

• 12 hours

• 9 hours

Which tasks are added to the priority list when there are two critical paths starting at different vertices?

• Task 6 and Task 7

• Task 4 and Task 5

• Task 2 and Task 3

• Task 8 and Task 9

What is the main drawback of Version One of the Critical Path Algorithm?

• Forward Scheduling

• Backflow Algorithm

• Resource Allocation

What is the final task added to the priority list in the example?

• Task 7

• Task 9

• Task 8

• Task 6
