In this paper, we consider a resource investment problem in which the goal is to maximize the net present value of the project cash flows. We call this problem as Resource Investment Problem with Discounted Cash Flows (RIPDCF) and we develop a heuristic method to solve it. Results of several numerical examples show that the proposed method performs relatively well.}, keywords = {Project scheduling,resource investment,Net Present Value,Heuristic methods}, url = {https://www.ije.ir/article_71574.html}, eprint = {https://www.ije.ir/article_71574_6908d8cdfbff6a13e818e3c12e03c7cc.pdf} }
