Summary
The scheduling processes is considered a complicated problem in project
management. In the past, many algorithms and paradigms had been developed in
order to reduce the project makespan as much as possible. The main objective in the
resource constrained project scheduling problem is the makespan, however, there are
other important objectives such as net present value minimization, minimization of
the hammock cost, maximization of robustness, etc, which are crucial to the project
success. This paper demonstrates some of these objectives by applying a conflict
repairing harmony search metaheuristic to academic problems. The algorithm shows
that the main objective should is not detrimentally affected by optimizing the second
criteria, and an interesting trade-off between the total makespan and the hammock
cost is apparent.
