Abstract
A method controls the elevators in an elevator group when destination floor call input is used and the traffic within the elevator group is to be optimized. According to the concept of the method, based on traffic intensity, a cost function is optimized by changing the number of cost criteria from one to several and back and weighting the criteria in different ways in the aforesaid cost function.
Claims11
Method for controlling the elevators in an elevator group when destination floor call input is used and the traffic within the elevator group is to be optimized, comprising the steps of:
- based on traffic intensity and traffic type, optimizing a cost function by changing the number of cost criteria and changing weighting of the criteria in the aforesaid cost function;
- in the aforesaid elevator group, using a destination floor call input device, the one of the elevators in the elevator group allocated for each passenger is indicated by the group control system of the elevator group;
- and
- using dynamic zoning to optimize passenger flow in the elevator group in busy traffic situation when traffic intensity of passenger flow exceeds a given preset limit value.
The method according to any one of the preceding claims, wherein in quiet traffic conditions, only one of the cost criteria of the aforesaid cost function to be optimized is optimized.
