Simulation data collection The evaluation of the efficiency of this building ’ s elevators Ryu Sook Jea Kim Sung Min Lee Yoo Chol Ma Yaowen

Data type Collect time period:5:30---6:30 Place: our building Elevator1 (only one for example) and elevator2 Number of people waiting outside at each floor Number of people go out of each floor
3
Some factors 1.elevator1 is stopped only at 1,4,5,6,7 floor, so there is no people waiting at 2,3,4 floor,and no people go out of 2,3,4 floor. 2.Because of the 1st factor, most people at one of 4,5,6,7 floor would go up or down of these four floor (or between the each 2 of these 4 floors) on foot, they do not use elevator, so we ignore the stop during each two floor of elevator in this case. (only from 1 to 5—7 or from 7---5 to1). 3. Usually, two elevators don’t come at the same time, so during one period, there are two different queues for two elevator, that means if some persons come to wait the elevator, they would waiting only one elevator coming, during which time, queue number of the other elevator is 0. 4.Because we collect data during the dinner time, all most all people move between 1st and 5,6,7 floor, so maybe it is more suitable for simulate operation of a elevator( operation of two elevators) during one special time 5.If person waiting to go down find elevator coming with “up moving” to sever other people in the lift to a upper floor, he will be one of the 2 queues according to the first coming time of these two lifts.
4
Collecting data: check two processes : find the number of people enter the elevator and go out at different destination during up and down processes at different time. Number out at floor

27
By collecting the data and make distribution, we evaluate and make sure what kind of data we should use for the distribution in simulation model.
