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.
