A new elevator group control system is proposed, The system learns dynamic
traffic flows by analyzing passenger traffic without prespecified patterns.
A genetic algorithm continuously generates dispatch functions according to
changes in passenger traffic. By considering the status inside elevators,
the directions of passenger movement, and the number of waiting passengers,
the system occasionally allocates multiple elevators for a single hall cal
l, which assists in reducing passengers' waiting time, Experimental results
showed up to 25% improvement over a system without the above features.
