Handling capacity is improved maximum 50%(*1) by handling capacity preference operation.

The FIBEE learns the patterns of daily congestion conditions. When the number of passengers increases, it allocates elevators to ensure passengers going to the same destination floor to use the same elevator as much as possible by searching for a similar pattern to the current situation from previously learned patterns and forecasting future passengers based on the data of searched pattern. This feature helps reduce the number of elevators stopping floors and improves handling capacity. According to our simulations, the handling capacity in morning up peak is improved by maximum 50% compared with conventional group controls. (*1)

  • (*1) Comparison with Hitachi conventional system. The improvement ratio of handling capacity may vary depending on the elevator specifications and conditions of use.
