In recent years, with the popularity of crime prevention system, which plays a positive role in the field of crime prevention. But a number of security facilities are wasted due to no risk optimization of crime prevention system. This paper firstly establishes a risk optimization model on crime prevention system. Secondly, combinatorial optimization technology is used to calculate this model. Finally, a concrete example is given out to verify the model reasonably. This optimization model can not only guide security facilities more rational allocation and scheduling scientifically and effectively but also fully utilizes the protection capability of crime prevention system. It has great theoretical significance to the planning and layout on crime prevention system in the future.
