1
Multiple dependency activity on node networks
(seminar)
2
Four possible dependencies between activities
Finish-to-start (or normal) dependency Start-to-start dependency Finish-to-finish dependency Start-to-finish dependency
3
Finish-to-start (or normal) dependency
a 3 b 7 9 2 4
4
Start-to-start (or lag-start) dependency
4 a 3 b 4 6 2
5
Finish-to-finish (lag-finish) dependency
4 a 3 b 5 7 2
6
Start-to-finish dependency
4 a 3 b 2 4
7
Dependencies can be used in combination
Start-to-start & finish-to-finish: 5 ? ? a 3 ? b 5 9 ? 7 2 6
8
Floats on multiple dependency networks
Total float = LFT – EST – Duration Early total float = LFT – EFT Late total float = LST – EST In case of multiple dependence free float cannot be calculated
