Elevator group control systems are the transportation systems for handling passengers in the buildings. With the increasing demand for high-rise buildings, multi-car elevator system (MCES) where two cars operate separately and independently in an elevator shaft are attracting attention as the next novel elevator system. Genetic network programming (GNP), one of the evolutionary computations, can realize...
In this paper, an improved approach is proposed based on an updating strategy using Genetic Network Programming (GNP) for the controller of Double-Deck Elevator System (DDES). Since the elevator controller has to deal with constant changes of its environment, our approach is proposed to deal with better the environment changes, resulting in a reduction of the waiting time and increasing the transportation...
Genetic network programming (GNP), one of the extended evolutionary algorithms was proposed, whose gene is constructed by the directed graph. GNP can perform a global searching, but it lacks of the exploitation ability. Since the behavior of GNP is characterized by the balance between exploitation and exploration in the search space, we proposed a hybrid algorithm in this paper that combines GNP with...
Elevator group control systems are the control systems that systematically manage elevators in order to transport passengers efficiently. With the increasing need for high-performance transportation systems in buildings, multi-car elevators where two cars operate separately and independently in an elevator shaft are attracting attention as the next novel elevator system.

Double-deck elevator systems (DDES) have been invented to improve the transportation capacity of elevator group systems for decades. There are several specific features in DDES due to its specific structure, i.e., two decks are vertically connected in one shaft. Even though the DDES could work well in a pure up-peak traffic pattern by cutting up to half of the stops in an elevator round trip, it becomes...
