Background In the related scheme, a fixed weight calculation method is generally adopted in a ladder dispatching strategy, namely a distance weight coefficient and a start-stop weight coefficient are preset as fixed values, the expected arrival time is calculated based on the distance between the elevator and the outbound floor, and the outbound is distributed according to the minimum time. The scheme is often inflexible when encountering special running conditions, can not timely adjust the elevator allocation logic according to passenger flow changes in the early and late peaks, adopts fixed partition operation to cause uneven allocation of transport capacity, can not dynamically adjust the fixed partition strategy when single or multiple elevators fail, obviously reduces the transport efficiency, and lacks special emergency treatment mechanisms when coping with sudden situations such as fire and the like. When it is desired to change the elevator allocation strategy, extensive adjustments to the codes are often required and quick response is difficult to achieve.
