A two-stage approach with softmax scoring mechanism for a multi-project scheduling problem sharing multi-skilled staff

作者：

Highlights：

• A two-stage model is established for the problem studied in this paper.

• A two-stage approach with softmax scoring mechanism (TSA-SSM) is developed.

• TSA-SSM performs better than compared methods for most of the problem subsets.

• TSA-SSM is further verified by solving the de-coupled problems.
