## Study Notes

### Activity on Node and Activity on Arrow

• The 'Activity on Node' method involves attaching activities and times to vertices.
• The 'Activity on Arrow' method involves attaching activities and times to edges and starting and finishing at a vertex.

### Network Diagram Construction

• When constructing networks, students can consider outsourcing tasks while showering, representing duration and interdependencies.

### Network Diagram Elements

• In the third diagram, a dummy activity X is introduced with no weight.
• 'Source' in a network diagram refers to the starting point, typically Australia in the context of travel routes between Australia and China.
• 'Sink' in a network diagram typically represents the ending point.

### Network Analysis

• The 'maximum-flow minimum-cut' theorem helps determine the maximum flow and minimum cut in a network.
• The critical path in a project network is the path with the longest duration.

### Time in Project Management

• Earliest Starting Time (EST) represents the earliest time an activity can start.
• Float Time in a project network is the amount of time an activity can be delayed without affecting the overall project duration.
• Latest Finish Time (LFT) indicates the latest time an activity can finish.

### Critical Path Analysis

• Forward scanning is used to find the earliest starting time of each activity in a project network.
• The start vertex is assigned an EST of zero in forward scanning.
• Backward scanning is used to find the latest finish time of each activity in a project network.
• LFT stands for Latest Finish Time in backward scanning.
• When two or more paths join in forward scanning, the maximum total is selected.

### Minimum Cut

• When finding a minimum cut, only saturated edges will be included.
• It is possible for saturated edges to exist that are not part of a minimum cut.

### Teaching and Practice

• The teacher models maximum flow and minimum cut in class.
• Students practice finding maximum flow and minimum cut in a student activity.
• Sample questions related to maximum flow and minimum cut can be found in a provided document.
• Identifying and addressing students' misconceptions is important in teaching.
