The resource-constrained project scheduling problem (RCPSP) is a well-known and widely studied topic. The underlying problem assumes that non-preemptions and that constant resources are restrictions imposed on project activities, which are to be scheduled, subject to precedence relation and limited resource constraints. | New procedures with new activity assumptions for solving resource constrained project scheduling problems Journal of Project Management 5 2020 41 58 Contents lists available at GrowingScience Journal of Project Management homepage New procedures with new activity assumptions for solving resource con- strained project scheduling problems Samer Ben Issaa and Yiliu Tua a Schulich School of Engineering Department of Mechanical and Manufacturing Engineering University Drive 2500 .
