Abstract: In a rapidly changing and highly uncertain environment, Petri
net-based project management systems can be used in the rescheduling (control
reconfiguration) of projects, when unforeseen changes occur or new data
estimates become available. However, having to reschedule the project after it
has started can result in significant suboptimality due to increased cost. In this
paper, we present a solution method which is, to a large extent, robust to data
uncertainty and does not require rescheduling for a certain predefined level of
uncertainty. We build the model using robust optimisation techniques which
address data uncertainty in project parameters, by taking advantage of risk
pooling and without knowledge of their probability distributions. We illustrate
