Study Notes
Network Development of PERT and CPM
Activity-on-Arrow (AOA) Diagram
- Used in CPM (Critical Path Method)
- Activities are represented by arrows
- Nodes represent events or milestones
- Each arrow has a direction, indicating the sequence of activities
- Duration of each activity is written on the arrow
Activity-on-Node (AON) Diagram
- Used in PERT (Program Evaluation and Review Technique)
- Activities are represented by nodes
- Arrows connect nodes, indicating the sequence of activities
- Each node has a duration, indicating the time required for the activity
Network Development Steps
- Define the project scope: Identify the tasks and activities required to complete the project
- Identify the dependencies: Determine the sequence of activities and their dependencies
- Create the network diagram: Draw the AOA or AON diagram, including all activities and their dependencies
- Estimate the activity durations: Assign a duration to each activity, based on the resources required and the complexity of the task
- Determine the critical path: Identify the sequence of activities that determines the minimum duration required to complete the project
Network Analysis Techniques
- Forward Pass: Calculate the early start and finish times for each activity
- Backward Pass: Calculate the late start and finish times for each activity
- Float Calculation: Calculate the slack or float for each activity, indicating the amount of time an activity can be delayed without affecting the project duration
Advantages of Network Development
- Improved project planning: Helps to identify the critical path and potential bottlenecks
- Enhanced scheduling: Enables the creation of a realistic project schedule
- Better resource allocation: Allows for the efficient allocation of resources to activities
- Increased project control: Facilitates the monitoring and control of project progress
