An Optimization via Simulation approach for the preemptive and non-preemptive multi-mode resource-constrained project scheduling problems

In this paper a novel modelling and solving method has been developed to address the so-called resource constrained project scheduling problem (RCPSP) where project tasks have multiple modes and also the preemption of activities are allowed.To solve this NP-hard problem, a new general optimization via simulation (OvS) approach has been developed wh
