As shown in Table 4, in the case of normal
traffic results of type-1 fuzzy logic is better
than type-2 fuzzy logic. But in the case of
heavy traffic (before and after lunch time),
results of type-2 fuzzy logic shows a
decrease in the average waiting time and
long wait probability but the power
consumption is increased a litte. The
comparison in the total period from 12:00 to
15:00 shows that the average waiting time
is improved by 9.2 % and the long wait
probability by 12.0 %.
We have simulated several times using
other traffic data. By the simulation the
average waiting time is improved by 7 –
20% and the long wait probability by 11 –
30 %.
VI. CONCLUSION
In this study the type-2 fuzzy was used to
determine the area-weight which is one of
the most important parameters of the hall
call assignment method in the elevator
group control system. To analyze the
performance of the system, we simulated
the proposed system and a conventional
system. We could see that our system
improved the system performance by 4 –
20% compared with the type-1 fuzzy
controller.
