A probabilistic scheduling model for software projects is presented. The model explicitly takes a scheduling strategy as input. When the scheduling strategy is fixed, the model outputs a probability distribution for the project completion time or cost. By applying stochastic optimization techniques, schedules for software projects can be computed which minimize the development time or cost with...

Assigning staff to specific duties according to their contract, qualifications, skills, etc. within a working environment characterised by multi-disciplinarity and statutory regulations is problematic. This paper discusses an approach to nurse rostering, using a strategy of distributing the computational effort required in the scheduling process. The technique involves a hybrid approach that de...

In this paper, we present an extension of the classical Resource Constrained Project Scheduling Problem (RCPSP). We present a new type of resource constraints in which staff members are involved. We present a new model where staff members can have several skills with different proficiency, i.e., a staff member is able to perform more than one kind of activity as well as the time need is complet...

In the presence of imprecise management targets, staff preferences, and patients’ expectations, the healthcare staff scheduling problem becomes complicated. The goals, preferences, and client expectations, being humanistic, are often imprecise and always evolving over time. We present a fuzzy genetic algorithm (FGA) approach for addressing healthcare staff scheduling problems in fuzzy environme...

PURPOSE The purpose of this paper is to describe current physician scheduling and concomitant opportunities for improvement in public hospital departments in Sweden. DESIGN/METHODOLOGY/APPROACH A total of 13 departments spread geographically across Sweden covering seven different specialties participated in the study. Data were collected through interviews with individuals involved in creatin...

Resource allocation and staff scheduling has been a long studied topic, and there is a growing amount of research addressing such issues in the healthcare industry. Few studies, however, have focused on a visualization system to assist emergency department (ED) healthcare personnel perform patient assignment. This project provides an initial prototype tool to help medical staff make patient sch...
