Modelling a project
- A precedence table (aka dependence table) is a table that shows which activities must be completed before others are started.
- An activity network is a more efficient way of representing the information in a precedence table.
- In an activity on arc network, the activities are represented by arcs and the completion of those activities, known as events, are shown as nodes.
- Each arc is labelled with an activity letter. The beginning and end of an activity are shown at the ends of an arc and an arrow is used to define the didrection.
- The nodes are numbered starting from 0 (sometime 1).
- Number each node as it is added to the network
- The final node is called the sink node
