ABSTRACT
For example, the critical path method is the most
common technique employed today for drawing up
robust schedules. Koo et al. (2007) present a for-
mal identification and re-sequencing process using
the Critical Path Method (CPM) which supports
the rapid development of sequencing alternatives
in construction schedules. Pontrandolfo (2000)
emphasizes the complexity of construction projects
and the uncertainty that surrounds any estimation
of the length of a certain activity, resulting in a
higher criticality of project scheduling. Addressing
this problem, he uses PERT-state and PERT-path
techniques, focusing on network complexity and
time uncertainty. Biruk et al. (2008) present a new
methodology for project scheduling with repetitive
processes using a Petri-nets based approach.
