Abstract: With this thesis we aim to create an efficient scheduling algorithm for elevators that can move in multiple directions and establish if and when the algorithm is efficient in comparison to algorithms constructed for traditional elevator algorithms. To measure efficiency, a simulator is constructed to simulate an elevator system implementing different algorithms. Because of the challenge of constructing a simulator and since we did not find either a simulator nor any algorithms for use in multidirectional elevator systems publicly, we decided to focus on these subjects. The results in this thesis leads us to the conclusion that a multidirectional elevator algorithm is efficient to use under certain circumstances. If the traffic is concentrated to one floor in the building the multidirectional elevator system performs poorly but when the traffic is spread out it outperforms traditional elevators algorithms. We hope that this research will inspire to further research in the area of multidirectional elevator systems.
