Recent results on resource-constrained project scheduling with time windows are reviewed. General temporal constraints (resulting from minimum and maximum time lags between project activities), several different types of scarce resources, and a large variety of time-based, financial, and resource-based objective functions are considered. Emphasis is placed on an order-based structural analysis of the feasible region of project scheduling problems and a classification and discussion of objective functions important to practice, which can be exploited for constructing efficient solution procedures. After those structural issues, methods for solving time-constrained project scheduling problems are proposed. Next, the resolution of conflicts for renewable, allocatable, synchronizing, changeover, and cumulative resources and thus the solving of corresponding resource-constrained project scheduling problems …
