New Approach in the Development of Elevator Group Control Algorithms

Group control algorithms are designed in order to increase the transport capability of elevator groups and to improve various factors such as waiting time of passengers. During the past ten years a significant improvement of performance has been gained owing to the development of technology, hardware and software. However, the objectives of the optimization (for instance minimization of waiting time) are still not clearly defined and remain ambiguous. It cannot be assured that the system optimizes exactly what is expected. The paper describes our approach which consists first a better definition of objectives (factors related to passengers are projected in the factor space), secondly the design of an evaluation module and finally the integration of the evaluation module into a target system.
