Abstract: There are numerous of people that work in office buildings. For many of them, using an elevator is a daily practice. Being able to access a time efficient elevator is therefore of great interest for many people. Having to spend unnecessary time either inside an elevator or waiting for the elevator to arrive to you is not something that people appreciate. In order to achieve an efficient elevator, the elevator control system needs to be optimized for building that the elevator will be used in. This thesis investigates the time efficiency of two different traditional elevator control systems in a small office building in order to find out which of them that is the most time efficient. In order to compare the two elevator control systems a simulator was developed in Java. The simulator simulated one year of elevator usage in an office building with one elevator, 10 floors and 100 persons. The results of the simulation show that the usage of a non-directional collective control system (NDCCS) caused an approximately 66% shorter average waiting time, an approximately 5% longer average travel time making the average total time 54% shorter than when using a full collective control system (FCCS). The conclusion was that the NDCCS was the most time efficient in this specific building.
