Abstract: To improve the mathematical model，in this paper，based on the remote image processing and modified particle swarm optimizers，a new method is introduced to the research of spatial decision support system for location selection of factory.As a remarkable improvement on the conventional methods，the mathematical model can be easily established by fully utilizing positional information and attribute information in GIS.

Key words: spatial decision support system, location selection, RS image processing, particle swarm optimizers

摘要： 利用遥感图像处理技术和改进的粒子群优化算法，提出了一种结合遥感图像处理技术的企业选址算法，可以充分利用GIS的空间和非空间信息，考虑的因素更为全面，极大地避免了人为因素的影响，是对选址决策支持系统的改进。
