Scheduling projects at the activity level increases the complexity of decision making of project portfolio selection but also expands the search space to include better project portfolios. An integer programming model is formulated for the project portfolio selection and scheduling problem. An iterative multi-unit combinatorial auction algorithm is proposed(More)
An ant colony algorithm is proposed to improve the net present values of resource-constrained projects since the net present value is a critical criterion for a project with a long time span and considerable cash flows. The algorithm adaptively adjusts the allocation of scarce resources according to the pheromone generated by artificial ants in the previous(More)
