Quantitative evaluation of crime prevention system in the museum

With the rapid development of industrialization and urbanization, crime prevention issues become serious in China each day. Although various security facilities have played a positive role in the field of crime prevention, defects exist in poorly designed systems targeting detection, delay, and response. Due to the absence of theoretical methods and technical means for scientific evaluation on the effectiveness, it is difficult to support a complete and efficient deployment of a comprehensive prevention and control system. Therefore, it is a major strategic task to improve effectiveness evaluation techniques and promote the objective evaluation of the effectiveness in such area. In this paper, firstly, adversary sequence diagram and intrusion path analysis model are established to describe the facilities and all the intrusion path of crime prevention system. Secondly, the path prompt detection analysis method of crime prevention system is introduced to evaluate its effectiveness quantitatively according to the adversary sequence diagram. Lastly, quantitative analysis on three elements (detection, delay, and response) of crime prevention system is presented with an imaginary example in the museum crime prevention. The results indicates that the path prompt detection analysis method works effectively to find the weak point of the crime prevention system in the museum, and meanwhile we can also get the high cost-effectiveness improved measures. It is an effectiveness approach to evaluate the overall effectiveness of the system.
