ABSTRACT:
A group elevator control includes a call allocation device which automatically adapts to optimization criteria and traffic conditions so that an optimum call assignment is achieved. The device includes a solution selection module which calculates starting from a first time predetermined solution, further possible solutions for the call assignment which are fed to a simulator module. A traffic model module supplies possible passenger number and destination floor data to the simulator from which is generated factors data for the solutions, the factors data relating to passengers and/or elevator components. The factors data is fed to a calculation module, which uses a calculation function and optimization criteria data from the elevator control to generate another call allocation solution to the solution selection module which compares each another call allocation solution with the previous best solution to select the best of all possible solutions for the call allocation.
