Project Scheduling

Project scheduling problems are, generally speaking, the problems of allocating scarce resources over time to perform a given set of activities. The resources are nothing other than the arbitrary means which activities complete for. Also the activities can have a variety of interpretations. Thus, project scheduling problems appear in a large spectrum of real-world situations, and, in consequence, they have been intensively studied for almost fourty years. Almost a decade has passed since the multi-author monograph: R. Slowinski, 1. W~glarz (eds. ), Advances in Project Scheduling, Elsevier, 1989, summarizing the state-of-the-art across project scheduling problems, was published. Since then, considerable progress has been made in all directions of modelling and finding solutions to these problems. Thus, the proposal by Professor Frederick S. Hillier to edit a handbook which reports on the recent advances in the field came at an exceptionally good time and motivated me to accept the challenge. Fortunately, almost all leading experts in the field have accepted my invitation and presented their completely new advances often combined with expository surveys. Thanks to them, the handbook stands a good chance of becoming a key reference point on the current state-of-the-art in project scheduling, as well as on new directions in the area. The contents are divided into four parts. The first one, dealing with classical models -exact algorithms, is preceded by a proposition of the classification scheme for scheduling problems.

The problem of allocating scarce resources over time to perform a given set of activities - that is, project scheduling - appears in the vast spectrum of real-world situations. Over the last forty years project scheduling problems have been carefully studied, resulting in a considerable body of knowledge. Recently, however, the power and ubiquity of the computer has had a pronounced effect on research in project scheduling and project scheduling models. As a result, considerable progress has been made in all directions of modeling and finding solutions to these problems. This volume is a state-of-the-art treatment of Project Scheduling in general and of recent developments in particular. Part I deals with classical models. By classical model' we mean the deterministic problems involving discrete resources only and the evaluation of schedules on the basis of a single criterion. This term covers a wide variety of problems, including (discrete) resource-duration interaction, i.e. multi-mode models. Part 2 deals with heuristic algorithms for these models. It is complemented by chapters treating such important problems as benchmark instances, interval capacity consistency tests, and the evolution of software quality for (classical) project scheduling problems. In Part 3 the most important new or non-classical' models are considered. These include probabilistic and fuzzy models, and continuous resources as well as multi-criteria formulations and knowledge-based systems. Part 4 contains some important extensions and/or applications of the project scheduling problems considered in the previous chapters.
