Abstract

The present invention relates to a technique for assigning an optimum state of an exhalation to an elevator in a military management system of an elevator. In the conventional military management system, allocation and control of exhalation are performed on the basis of predicted data, There is a defect that the utilization efficiency of the predicted traffic flow is lowered because indirect consideration is made without directly considering the hole call to be generated.

Accordingly, it is an object of the present invention to provide a method and apparatus for calculating a predicted ride factor of a group management elevator, calculating a predicted hall call for each section and direction, calculating a predicted hall call occurrence probability for each section and direction, The probability of occurrence and the previously registered hall call can be appropriately adapted to the change of traffic demand by the service allocation of the elevator by using the branch-and-bound technique, thereby improving the overall allocation performance .
