Optimal Positioning of Elevator Hoistways in Buildings based on a Simplified Circulation Model

In modern multi-storey buildings, the location of elevator systems is a very crucial factor regarding the efficiency of transportation service and the comfortable and easy on-floor circulation. The present paper proposes a method which, after the partition of a typical floor of a commercial building into cells by a grid, correlates architectural and circulation data for the formulation of functions and matrices that demonstrate numerically the architecture of the floor, the design of circulation spaces and the presented need for elevator service in each cell. Then, weighted Euclidean norms and modified heuristic search algorithms are used to find the position of the elevator hoistway that fits the existing architectural plan and is closest to the point of floor’s circulation paths that presents the minimum mean walking distance from the entrances of the areas that host floor’s population. A case study demonstrates effectively the proposed method.
