Optimization of Group Elevator Scheduling With Advance Information
Group elevator scheduling has received considerable attention due to its importance to transportation efficiency for mid-rise and high-rise buildings. One important trend to improve elevator systems is to collect advance traffic information. Nevertheless, it remains a challenge to develop new scheduling methods which can effectively utilize such information. This paper is to solve the group elevator scheduling problem with advance traffic information. This problem is difficult due to various traffic patterns, complicated car dynamics, and combinatorial explosion of the search space. A two-level formulation is developed with passenger-to-car assignment at the high-level and single car dispatching that is innovatively formulated as passenger-to-trip assignment at the low-level. Detailed car dynamics are embedded in simulation models for performance evaluation. Taking advantage of advance information, a new door action control method is suggested to increase the flexibility of elevators. ...
