Description:
This study assesses the quality of seven commercial project management systems to perform finite scheduling. We give a brief survey of the way commercial project management systems work and especially how they perform finite scheduling. Since the implemented methods are proprietary, we measure the quality of the Software in terms of the deviation from a strong lower bound of the minimum makespan. As benchmark instances we use a set of problems generated under a factorial design. Statistical tests are performed in order to investigate the impact of the problem parameters and to detect significant differences between the quality of the Software packages.
