Abstract:
1. Method for controlling the elevators belonging to an elevator group based on the calls given, in which the elevator comprises one or more elevator cars disposed in the same elevator shaft, and in which method a genetic algorithm is used, according to which algorithm: at least one allocation option i.e. chromosome is formed, which chromosome contains call data and elevator data for each active landing call or destination, which data i.e. genes together determine the elevator car serving the landing call or destination call; for each chromosome a value of the cost function is determined; at least one chromosome with respect to at least one gene is formed; for each chromosome formed a value of the cost function is determined; the forming of chromosomes is repeated, until the exit criterion is fulfilled; on the basis of the values of the cost function the best chromosome is selected; and the elevator cars are directed to the given calls according to the selected best genes of the chromosome, wherein the method further comprises the phase: information about the run type i.e. the run type gene is linked to the chromosome in connection with each call data and each elevator data, in which run type gene the run type determines the speed profile, according to which the elevator that owns the elevator car travels between the departure floor and the call issuing floor defined by the call gene linked to the run type gene.
