The demand for elderly care services has increased owing to the aging society. Daytime care facilities provide rehabilitation services to the elderly, such as massage and training, which use machines. In these facilities, rehabilitation equipment is used by staff to take care and assist the elderly, particularly in walkable activities. Accordingly, the service productivity of the staffs can be improved by reducing the total flow. The total flow among the staffs can be reduced by placing the equipment closer. However, equipment should be placed separately to avoid injuries caused by tripping on the rehabilitation equipment. Two goals are considered for minimizing the total flow of the staff and maximizing the remoteness of equipment. This paper proposes a layout planning business model in a daytime care service for rehabilitation equipment with the two goals for the total flow of the staff and the remoteness of equipment by the quadratic assignment problem (QAP). First, the QAP problem is formulated to integrate the minimization of the total flow and maximization of the value of remoteness by weighting. Next, an actual rehabilitation facility and its staff are surveyed. Finally, numerical experiments are conducted, and the effects of the total flow and remoteness of the equipment are discussed.
