A survey of project scheduling problems since 1973 limited to work done specifically in the project scheduling area (although several techniques developed for assembly line balancing and job‐shop scheduling can be applicable to project scheduling): the survey includes the work done on fundamental problems such as the resource‐constrained project scheduling problem (RCPSP); time/cost trade‐off problem (TCTP); and payment scheduling problem (PSP). Also discusses some recent research that integrates RCPSP with either TCTP or PSP, and PSP with TCTP. In spite of their practical relevance, very little work has been done on these combined problems to date. The future of the project scheduling literature appears to be developing in the direction of combining the fundamental problems and developing efficient exact and heuristic methods for the resulting problems.

In a multi‐item environment with a joint set‐up cost structure considerable savings may be realised by co‐ordinating the replenishments. This article presents a unified survey of the inventory control literature designed to capture the models that fit in this frame. In general these models are complex and require a great deal of computational effort to obtain an exact solution. The literature relies mainly on heuristic procedures.

Surveys multiple‐stage production planning literature to reveal that this sizeable body of research is largely inspired by single‐item production planning. Suggests several promising research opportunities, including the possible development of scheduling techniques not derived from older, single‐item procedures. Highlights the need for further comparative testing between existing “improved” techniques, as well as the wealth of work yet to be done in multiple‐stage production planning with limited resources and possible extensions to supply‐chain management.
