Abstract
Techniques for the management of resources in project-type planning and scheduling models have received increasing attention in recent years. Development of new procedures has occurred at a rapid rate, as evidenced by the growing tide of publications in the literature and widespread promotion of new “systems” for resource management by commercial organizations. The first previously-published survey of developments in this field was done by the author in 1966 and much has taken place since then. The development of new procedures has been so rapid, in fact, that it has been difficult to gauge both the existing state of the art and the trend in current developments. This paper is an attempt to categorize the existing procedures, define the state of the art and indicate the directions of continued progress.
