Abstract:

Optimizing fire station location to improve emergency rescue efficiency is an urgent issue in urban development. This study investigates fire station location from three aspects: model construction, solution, and evaluation, aiming to optimize the spatial layout of fire stations. Firstly, based on differences in station attributes and fire response demands, we classify risk levels and set corresponding response times. Considering factors such as cost, coverage rate, and response timeliness, we adopt a multi-objective hierarchical optimization modeling approach to establish a two-level objective function of quantity and distance. Secondly, using the road network, we define a path distance measure and replace traditional linear constraints with fuzzy nonlinear membership functions, thereby constructing a fuzzy multi-objective hierarchical location model based on path distance, named R-NLSM. Finally, the fuzzy membership functions are embedded into both genetic algorithm (GA) and particle swarm optimization (PSO) algorithms, and the two algorithms are employed to solve the model. Experimental results show that the overall response coverage rate increases by 16.69 percentage points after optimization, demonstrating the effectiveness and stability of the proposed model. Moreover, the model improves the matching between different risk levels and fire rescue efficiency, and ensures timely response for highrisk demand points. This work provides a methodological reference and technical pathway for fire station location and layout optimization.
