project networks
Project Networks
  • Activity on node
    • Most popular
  • Activity on arrow
    • Not used
from project networks we determine
From project networks, we determine
  • The project duration
  • The critical path
  • Tasks on the critical path
  • Tasks not on the critical path
  • Slack associated with non-critical tasks
  • Earliest start, earliest finish, latest start and latest finish times

notation
Notation
  • ES – earliest start for the node, assumed to be at the beginning of the day
  • EF – earliest finish for the node, assumed to be at the end of the day
  • LS – latest start for the node, assumed to be at the beginning of the day
  • LF – latest finish for the node, assumed to be at the end of the day
  • N -- the label of the node (task, step, activity)
  • K -- the duration of the node ( number following the slash)
precedence relations
Precedence Relations
  • With FS (FINISH/START) relationships, a successor activity does not start until all of its predecessors are
