A multi-objective multi-period mathematical programming model for integrated project portfolio optimization and contractor selection.

ABSTRACT: This paper addresses the challenges of project portfolio optimization and contractor selection through two proposed scenarios. In the first scenario, two separate mixed-integer mathematical programming models are presented: one for project portfolio optimization and the other for contractor selection. In this approach, the decision variables from the project portfolio optimization model are treated as parameters in the contractor selection model. In the second scenario, an integrated mixed-integer mathematical programming model is introduced to simultaneously address both project portfolio optimization and contractor selection. Both scenarios consider multiple objectives, such as profit, risk, technical capability, and costs, along with numerous constraints, including relationships, inflat
