Distribution management method and device of elevator group control system and medium

The invention discloses a distribution management method and device for an elevator group control system and a medium, and the method comprises the steps: distributing an elevator with the minimum predicted arrival time as an actually distributed elevator when an out-of-hall call registration is generated in a certain direction of a certain floor; in the elevator running process, the predicted arrival time of each elevator for calling and registering outside a hall of a certain floor and direction is compared and calculated, additional distribution is carried out except initial distribution, and subsequent processing is carried out on the additional distribution according to the change of the running state of the elevator. An enforceable formula of the comparison calculation and the subsequent processing is given. By adding the virtual allocation elevator, the elevator response with the shortest arrival time of calling and registering outside the hall is realized, the phenomenon that the elevator arriving at
