Abstract
This paper deals with the resource-constrained project scheduling problem with
exible
work pro les. In this problem, a project contains activities interrelated by nish-start-type precedence
constraints with a time lag of zero. In many real-life projects, however, it often occurs that only one
renewable bottleneck resource is available and that activities do not have a xed prespeci ed duration and
associated resource requirement, but a total work content, which essentially indicates how much work has
to be performed on them. Based on this work content, all feasible work pro les have to be speci ed for
the activities, each characterized by a xed duration and a resource requirement pro le. The task of the
problem is to nd the optimum work pro le and start time of each activity in order to minimize the project
makespan. We propose a procedure to nd all feasible work profiles of each activity and we use a genetic
algorithm with a new crossover operator to schedule the activities. Computational results on a randomly
generated problem set are presented.
