Today one of the world’s problems is queues and waiting in lines takes a lot of nerves and time. Sociologists, psychologists and economists all over the world are trying to solve this problem.
One of the oldest solutions is multi-server queues, but it is fairness, because some lines move faster than another. The researcher Jacob Hornik has discovered that perception of waiting period was one third longer than real waiting time. So, the main problem is how to make perception time queues shorter. Some businesses have come out with interesting solutions. In 1950s high-rise hotel had problems with lines for elevator. After some time administrators found a simple solution to put a large mirrors next to elevator doors, so now people were too busy smartening up. One airline discovered that people must every time wait seven minutes for the luggage, while other passengers with no luggage leave airport earlier. To solve this problem, airlines begin parking airplanes at the other end of terminal, so passengers need to make their way through a seven minute distance.
To sum up, problem of queues still exist and scientists are still trying to find better solutions.
