Abstract


In this study, a load balanced nurse-scheduling model is developed. A case problem of a local hospital in Ratchaburi
province is used to test the model in order to improve the existing manual method. There are three working shifts,
morning shift, afternoon shift and night shift in the hospital. The load balance is one of factors that affects the nurse’s
preferences. The objective of the study is to balance the load of each shift for all workers. The min-max objective is
applied to minimize the maximum deviation of the average load of each shift. Goal constraints is applied to determine
the plus and minus deviation from the average load of each shift. The proposed model is solved by the Premium Solver
on Microsoft Excel. It was found that the balanced load is improved.

Key Words: Nurse scheduling problem; Load balancing
