中文摘要：
大型活动举行期间,政府采取临时车辆管制来疏导交通流量。企业采取物流路径重构的应急措施,使原有供应链能够持续。设立了一个制造商,一个供应商,一个应急车辆转换点,建立（r,Q）库存模型。比较了物流路径中断前的原策略和物流路径重构后供应链协调策略的库存成本差异;比较了物流路径中断后供应链协调策略和非供应链协调策略库存成本差异,推导了最大成本损失比例。本文认为政府应对需要进行物流路径重构的企业提供补贴,或提供免费的应急点建设;企业应尽量采取供应链协调策略减少库存成本增加。
英文摘要：
In the time of the big event in a city, the Government will take the vehicles restriction policies. And the companies have to rerout the logistics to manage the disruption risk. Considering one manufacturer, one supplier, one contigency vehicles transfer point, we build several（r,Q） inventory models. Compare the inventory holding cost difference between orginal inventory strategy before rerouting and supply chain coordination strategy after rerouting; compare the inventory holding cost difference between supply chain cooridination strategy and non-supply chain coordination strategy after rerouting and get the result of worst-case performance. The conclusion is： if the vehicles restriction happen, the government should consider to provide compensation to the companies to implement the logistics rerouting strategy or provide free contigency transfer facilities. From the companies side, they should try to make use of supply chain cooridination strategy instead of the others.
