A priority rule-based heuristic for resource investment project scheduling problem with discounted cash flows and tardiness penalties (Q1036260)

Summary: The resource investment problem with discounted cash flows (RIPDCFs) is a class of project scheduling problems. In RIPDCF, the availability levels of the resources are considered decision variables, and the goal is to find a schedule such that the net present value of the project cash flows optimizes. In this paper, we consider a new RIPDCF in which tardiness of project is permitted with defined penalty. We mathematically formulated the problem and developed a heuristic method to solve it. The results of the performance analysis of the proposed method show an effective solution approach to the problem.
