RosterBuilder: An Architecture for Airline Rostering

Airlines rely on crew scheduling tools to resolve crew utilization and cost issues and to address service quality and employee satisfaction issues. This article presents the architecture for a reference framework for flexible rostering at airlines and illustrates its integration into modern computing and communication environments. The analysis focuses on functional requirements applicable to most airlines using a rostering concept and specifies those requirements in use case diagrams that follow the UML formalism. Reflecting the need for flexibility, scalability, and ubiquitous access to information, this article proposes a component-based system architecture that can easily be adapted to end users' needs.
