Most of the elevator group control
hall call assignment
method
to a passenger’s call. In this case, the
elevator group control system considers the
current situation of a building to select the
most appropriate elevator.The hall call
hall call
to the elevator having the smallest
evaluation function
area-weight
which affects the evaluation-function value
of the elevators in the area close to the hall
call.
There have been many researches in this
area utilizing numerous approaches in
designing the most effective elevator
supervisory controller. Various strategy
based on fuzzy logic system have been
studied to control the elevator group. C. B.
Kim [1] proposed a fuzzy model to
determine the area-weight. In another work,
C.B. Kim proposed a control strategy
generation method and fuzzy elevator group
control system (FEGCS) in [2]. The control
strategy of FEGCS is made using the
classification of the passenger traffic and
system manager’s requirements, and the
hall calls are assigned to suitable elevators
by generated control strategy. In [3], R.
Gudwin introduced a fuzzy group supervisory
controller with context adaptation to
accommodate different traffic patterns.
This paper explores the use of Type 2
Fuzzy system, which is well known for its
powerful in handling an uncertainties [4], to
determine the area-weight parameter.
Although there are a lot of work on type 2
