Constrained resource project scheduling subject to material constraints

Constrained resource project scheduling techniques schedule project activities subject to finite constraints on the availability of non-storable resources such as labor and equipment without consideration of constraints resulting from material requirements. Projects are frequently delayed and resources are wasted when project activities are delayed due to material shortages. A heuristic procedure is presented here for scheduling large projects subject to the availability of all necessary resources, including materials, manufactured components, facilities, equipment and labor as well as the acquisition lead times required by these resources. Results are listed for tests involving both benchmark and actual problems.
