Abstract: Spatial optimization of facility allocation that aims to form the spatial layout and dispatch plan of facilities is a typical high-dimensional multi-peak NP-Hard combinatorial optimization problem based on geographic information, operational research modeling, and urban planning. It is essential to improve the plan's quality to design and enhance the spatial optimization algorithm of facility allocation. This paper analyzes the critical characteristics in service facility allocation spatial optimization, introduces a real coding quantum evolution algorithm, and mainly establishes tetraploid quantum chromosome coding operator and capacity constraint operator for formulating the quantum evolution algorithm for spatial optimization of facility allocation (QEA-SOFA). Based on the emergency facility spatial optimization experiment, the QEA-SOFA algorithm can effectively improve the equality of the relocation optimization of emergency facilities by 66% compared with the real-coding genetic algorithm. The result demonstrates that the QEA-SOFA algorithm has better global search capability for high-dimensional multi-peak spatial optimization problems and has a more extensive search scale for local search of heterogeneous spatial regions, which reveals that the quantum evolution mechanism has a great deal of potential in solving geospatial optimization problems.
