Why to translate a network to a Gantt chart?

• Gantt chart is more readily to understood by
  unskilled people. It is especially useful when
  presenting to the top management.
• Progress can be easily displayed on it
• Visualise floats and activity times. Effective
  explanatory and teaching instrument.
• Resource allocation can be performed on it.

3
Two ways af translating networks into bar chart

• Calculating activity times and loacting these on
  the bar chart
• Drawing activities directily to a time-scale,
  using the node numbers ensuring correct
  relationships (time-scaled network)
• AoA type
• AoN type

4
The time-scaled network (AoA)

• Mark activities by nodes (events)
• Any dummy must be drawn in as a vertical line
  with its head and tail node-labels
• Activitiy bars will fall from top-left to
  bottom-right. Dependent activities are always
  lower in the chart.

Time-scaled AoN network (example 1)

• Re-draw the first AoA project as an AoN network

• On AoN networks start and finish activities
  should be created if thereis no single
  starting/ending activities.
