Recursive logic-based Benders’ decomposition for multi-mode outpatient scheduling
Efficient outpatient scheduling is becoming increasingly important for the overall cost effectiveness and treatment efficiency of a hospital. We consider a class of multi-mode appointment scheduling problems, with variable resource availability and resource setup times. These problems are frequently...

Modelling and solving generalised operational surgery scheduling problems
The term 'surgery scheduling' is used to describe a variety of strategic, tactical and operational scheduling problems, many of which are critical to the quality of treatment and to the efficient use of hospital resources. We consider operational surgery scheduling problems. The exact problem formul...
Integrated planning and scheduling in operational patient management
Multi-level Benders Decomposition for Multi-modal Outpatient Scheduling in Hospitals
On parallel local search for permutations
We investigate some ways in which massively parallel computing devices can be exploited in local search algorithms. We show that the substantial speedups that can be gained from parallel neighbourhood evaluation enables an efficient best improvement local search, and that this in turn enables furthe...
Operational activity scheduling in a hospital laboratory
The Surgery Scheduling Problem - A General Model
The term surgery scheduling is used about a variety of strategic, tactical and operational scheduling problems, many of which are critical to an efficient use of hospital resources. Our focus is on operational surgery scheduling problems, which are often NP-hard. The exact problem formulation varies...
A mathematical model for the nurse rostering system
The model we present in this report is mainly developed on work done together with the company Gatsoft AS. With minor changes and extensions, a version of the model has been implemented and delivered to Gatsoft as a plug-in to the rostering part of their software GAT. The model consists of two types...
