In this paper, a detailed model and an efficient solution methodology for the monthly
workshift and rest assignment of hospital nursing personnel is presented. A model that
satisfies the rules of a typical hospital environment based both on published research data
and on local hospital requirements is designed. A hybrid methodology that utilizes the
strengths of operations research and artificial intelligence was used for the solution of the
problem. In particular, an approximate integer linear programming (ILP) model is firstly …
