The project scheduling problem involves the scheduling of project activities subject to
precedence and/or resource constraints. Of obvious practical importance, it has been the …

We survey several viewpoints on the management of the planning complexity of multi-
project organisations under uncertainty. Based on these viewpoints we propose a …

A common problem at hospitals is the extreme variation in daily (even hourly) workload
pressure for nurses. The operating room is considered to be the main engine and hence the …

In this paper we investigate how to sequence surgical cases in a day-care facility. We
specify a multi-criteria objective function in which we minimize the peak use of recovery …

In this paper we study a resource constrained project scheduling problem in which the
resource usage of each activity may vary over time proportionally to its varying intensity. We …

Tactical planning of resources in hospitals concerns elective patient admission planning and
the intermediate term allocation of resource capacities. Its main objectives are to achieve …

Many engineering-to-order (ETO) organizations are multi-project capacity-driven production
systems in which capacity planning is of major importance in the order acceptance phase …

This paper describes the models, algorithms and implementation results of a computerised
scheduling system for the steelmaking-continuous casting process of a steel plant in Austria …

In practice, order acceptance and production planning are often functionally separated. As a
result, order acceptance decisions are made without considering the actual workload in the …

In Manufacturing-to-Order or Engineering-to-Order systems producing complex and highly
customised items, each item has its own characteristics that are often tailored for a specific …
