Abstract:

The space of multi story buildings is usually limited, and how to reasonably layout public facilities within the limited space to meet the needs of different user groups is a challenge. Therefore, this paper proposes an optimization design method for the utilization of public facilities in multi story buildings based on firefly algorithm. Establishing a public facility utilization optimization model with the optimization objectives of maximizing efficiency, fairness, and coverage, and using firefly algorithm to obtain the optimal solution of the model, in order to achieve the optimization design of public facility utilization in multi story buildings. The experimental results show that the proposed method has high efficiency, fairness, and coverage, indicating that the planning results of this method can ensure the rational utilization of public resources, benefit the target population, and cover the widest possible geographical area.

Key words: multi story buildings, optimization of public facility utilization, firefly algorithm, efficiency of use, coverage range
