Multi-shifts working condition is harder than the single shift one, and it is expected that the working condition be improved. One of approaches for the improvement is to make the work schedule so as to achieve the worker’s preference on it as large as possible. The preference depends on each of workers and it may vary with the time. Tackling with such a situation, an interactive multi-shift scheduling method is proposed in the paper. The method checks the feasibility of workers’ preferences, makes a fundamental shift schedule, and improves the schedule by shifts exchange between the workers. A necessary condition of a feasible schedule is clarified, and a prescreening procedure on the feasibility is developed. By the method, the workers’ preferences on shifts are reflected in the shift schedule as large as possible.
