| Abstract(in English) | In this study, we report some preliminary results to optimize operations for multi-car elevator systems. This study approaches the problem of obtaining optimal operations of multi-car elevator system on the premise that all information on users of that system is given beforehand. Such problem can be handled as a static optimization problem and we adopt the trip-based integer linear programming model which has been proposed by the authors for single-car elevator systems. That model is based on the notion of trip, which represents a uni-directional movement of an elevator, and has decision variables each of which represents an assignment of a user to a trip. The multi-car elevator system has such a distinctive difficulty that elevators in a same shaft have not to conflict. In the proposed model, that difficulty is represented as constraints which prohibit trips to overlap spatiotemporally. The proposed model is evaluated by solving 90 problem instances of small scale. |
