H a l a m a n

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.
