The conventional procedure to calculate the expected number of stops and the highest reversal floor of lift systems in up-peak condition with floors equally populated and passenger arrivals uniformly distributed on time, implies that the number of stops made by the lift is a random variable with a binomial distribution. This assumption is not true. The improved procedure described below to do this calculation allows us not only to find the correct expected values of these variables but also the detailed probability distribution of them.
Lift display and control specialist E-Motive has supplied a Lift Monitoring System to the new Constellation Place office tower in Los Angeles, California. The 35-story building, also known as MGM Tower for its lead tenant, is the first skyscraper of the 21st century to be built in Los Angeles.
