Due to the diversity of its objectives, the optimal spatial configuration process of public service facilities in indemnificatory communities is a multi-objective decision issue. As for the study on optimization for spatial configuration of indemnificatory community public service facility, it is important to find an objective, reasonable and effective method that can address multi-objective decision-making challenges. The method is also the foundation for achieving the effect of indemnification and building a harmonious society. Based on the overall objectives of "resource efficiency" and "maximum benefits", this paper builds the modified Multi-objective Genetic Algorithm (MOGA) model for optimizing spatial configuration of indemnificatory community public service facility, conducts an empirical simulation based on the case of the New Jiangqiao City in Jiading District of Shanghai, with the purpose of introducing the optimal spatial configuration solution for public service facilities. Compared with the ordinary GA-based results, the optimal spatial configuration of public service facilities based on modified MOGA is more reasonable and compact. The model improves the configuration theory for public service facilities in indemnificatory communities, which is of substantial theoretical and practical significance for creating more scientific and reasonable configuration of public service facilities in indemnificatory communities.Keywords:indemnificatory community;public service facility; Multi-objective Genetic Algorithm (MOGA), spatial configuration optimization
AIMS AND BACKGROUNDPublic service facility configuration is essentially a complicated multi-objective non-linear dynamic optimization decision-making issue. On the one hand, the configuration process must take into account the effects of various factors such as the location, accessibility and fairness of the public facilities as well as the interaction and interconnection with one another. On the other hand, during the multi-objective optimization for the configuration of public service facilities, the sub-objectives to be optimized simultaneously usually conflict with one another. The key to solving the optimization problem of spatial configuration of public service facilities lies in finding an objective and quantified balance solution (i.e. the Pareto optimal set) under the effects of multiple factors and during the multi-objective optimization.Current researches on the public service facility configuration mainly focus on the subjects of location, accessibility and fairness of facilities. For example, the study on location of public service facilities focuses mainly on their location optimization. Alcada-Almeida et al., (2009)designed a Gaussian diffusion model for optimal configuration of multi-objective spatial locationby using mixed integer and multi-objective planning. Teixeira and Antunes(2008) introduced a discrete rating configuration model for public service facility location and validated the effectiveness of the model through a scho...
