CUSTOMER SERVICE IN AN ELEVATOR SYSTEM DURING UP-PEAK

This article discusses passenger service in an elevator system during up-peak. There are several indicators describing elevator and passenge r service, such as round-trip time and interval, passenger waiting tim e, ride time inside a car and journey time. Well-known equations for e levator round-trip times and mean passenger waiting times are referred to. The elevator service time at an entrance floor is the time interv al between sequential elevator departures for upper floors. The time a passenger spends in an elevator traveling up to the destination door is different from the elevator service time. It depends on the destina tion floor, the number of intermediate stops before the destination, a nd the passenger loading and unloading times. New equations for the pa ssenger ride time inside the car and the total time a passenger spends in an elevator system (journey time) are deduced using transition pro babilities between the floors. Theoretical results are compared with s imulated results, and the validity of the theories is discussed. (C) 1 997 Elsevier Science Ltd.
