Resource constrained scheduling simulation model for alternative stochastic network projects Original Research Article

The paper presents a heuristic for resource constrained network project scheduling. A network project comprising both alternative deterministic decision nodes and alternative branching nodes with probabilistic outcomes is considered. Several renewable activity related resources, such as machines and manpower, are imbedded in the model. Each type of resource is in limited supply with a resource limit that is fixed at the same level throughout the project duration. Each activity in the project requires resources of various types with fixed capacities. The activity duration is a random variable with given density function.
