1 Project Background

There are four elevators in the basic teaching building of Shijiazhuang Railway University, and students are required to take the elevator downstairs every day. However, due to improper use of elevators by students, resulting in lower elevator utilization, wasting the students a lot of time. Therefore, it is necessary to design an elevator dispatching system to standardize students ' behavior and to maximize elevator utilization.

2 Purpose

Reduce the waiting time for the elevator, relieve the pressure of the elevator at the peak of the class, and fully improve the utilization of the elevator.

3 Survey data

(1) A total of 18 floors, 4 elevators, each with a limit of 15 people, weight limit 1150kg.

(2) 1, elevator 2nd only stop 1, 8-18 double-storey building, 3, 4th elevator only stop 1,8-18 single floor.

(3) Peak: 7:30--8:00,11:50--12:20,13:30--14:00,17:50--18:10, 18:30--19:00,20:40--21:10 upstairs number: 10~15 people, downstairs number: 10~15 people. and 7:30--8:00 and 13:30--14:00 and 18:30--19:00 students are mostly upstairs, 11:50--12:20 and 17:50--18:20 and 20:40--21:10 are mostly downstairs.

(4) Usual: The number of people is 0~3.

Elevator number	Docking floor	Population Limit/person	Quality Limit/kg	Elevator speed (s/layer)	Opening/Closing Time/s
1	8-18 Double Layer	15	1150	4	3
2	8-18 Double Layer	15	1150	4	3
3	8-18 Single Layer	15	1150	4	3
4	8-18 Single Layer	15	1150	4	3

(5) The passenger enters the door time: The peak period is about 9 seconds, usually is about 4 seconds.

(6) The stopping time of each layer is about 9 seconds.

4 Demand Analysis

(1) Elevators can reach each floor.

(2) Elevators do not stop at each.

(3) The elevator can identify the current floor and detect if it is overloaded.
