特殊時(shí)期地鐵安檢強(qiáng)化措施的優(yōu)化模型和社會(huì)福利分析
[Abstract]:It is necessary to strengthen subway security measures to prevent terrorist attacks during special periods such as major activities in cities. This paper analyzes the effect of adding hand-held metal detector to subway security inspection in special period, and compares it with normal subway security inspection measures. Firstly, the optimization model of normal subway security inspection and special subway security inspection is constructed. Secondly, the effects of hand-held metal detector and X-ray security detector on potential assailants, travel convenience and social welfare of ordinary passengers are compared in different situations. Finally, the sensitivity of important parameters is analyzed numerically. The research shows that the increase of hand-held metal detector in special period of subway security inspection can reduce the optimal precision requirement of X-ray security detector in physical inspection link, thus providing more convenience for ordinary passengers. But the normal security X-ray detector has higher detection accuracy and can identify potential attackers with greater probability. Only under the special conditions, the special period of subway security inspection can improve the overall social welfare.
