INTEGRATED DAYS OFF AND SHIFT PERSONNEL SCHEDULING

The two levels of personnel scheduling, that is, determination of the days an employee should work and determination of the time an employee should start each workday, are integrated. The integration allows constraints involving hourly fluctuations in demand and fixed work force size to interact. the objective is to minimize the cost of premium pay plus customer invonvenience due to understaffing. an optimal solution is attained via linear programming. In a realistic service system environment, the model outperformed an integrating heuristic by 13. 56%.
