An Annotated Bibliography of Personnel Scheduling and Rostering

A.T. Ernst, H. Jiang, M. Krishnamoorthy, B. Owens, D. Sier
2004 Annals of Operations Research  
Crew rostering is largely applied in transportation systems. The optimal duties obtained from crew scheduling are sequenced, in some optimal fashion, to form feasible lines of work.  ...  Crew rostering is then the process of choosing a set of the best lines of work for all employees. Tour scheduling in non-transportation systems is similar to crew rostering.  ...  This paper provides details of a method to roster crew at Swiss Air which was never implemented.  ...
