As the height of building grows, a request to enhance its transportation capacity has been increasing.
One of the solutions could be increasing the number of elevator shafts.
There, however, exists a dilemma that most of floor space is occupied by the elevator shafts if a lot of elevator shafts are installed.
Therefore, multi-car elevators (MCE) systems, which have several elevator cars in a shaft, are attracting people's attention.
Optimization of car control and call assignment is necessary to control MCE systems safety and transport passengers rapidly.
We have studied the optimization problem, which is called a car control and assignment problem in MCE systems, and proposed an integer programming (IP) formulation.
It, however, has a problem that it takes long time to solve.
In this paper, we formulate a mixed integer programming (MIP) model of the car control and assignment problem and evaluate through computational experiments.
The results show that we can solve the problem faster using the MIP model than the IP model. |
