What is the node network diagram & critical path for this
Transcribed Image Text:**Activity on Node Diagram: Critical Path Analysis**
For the activity on node shown, find the critical path and the expected duration of the project.
**Note:** P, x = Activity, duration in weeks
### Diagram Description:
The diagram is a network graph representing project activities and their durations. Each activity is labeled with a letter and a number indicating its duration in weeks. The nodes represent different stages of the project, connected by directed arrows showing the sequence of activities.
- **A (2 weeks):** Starts the project, leading to Activity B.
- **B (3 weeks):** Follows Activity A, leading to Activities C, D, and G.
- **C (1 week):** Concurrent with Activity D, leads to Activity E.
- **D (3 weeks):** Concurrent with Activity C, leads to Activity F.
- **E (4 weeks):** Follows Activity C, converges with F to lead to Activity I.
- **F (3 weeks):** Follows Activity D, converges with E to lead to Activity I.
- **G (2 weeks):** Follows Activity B, leading to Activity H.
- **H (5 weeks):** Follows Activity G, converges with other paths at the final node.
- **I (3 weeks):** Final activity, completes the project.
### Instructions:
Identify the longest path through the network to determine the critical path and calculate the total duration of the project. The critical path will be the sequence of activities that determines the project's minimum completion time.
