汽车作为一种特殊的消费品,它的购买不是消费的终止,而是消费的开始。随着我国汽车制造业进入微利时代,汽车服务业呈现出前所未有的活力,如雨后春笋般迅速崛起,成为汽车行业又一新兴的利润增长点,同时以迅猛的速度朝着产业化、专业化的方向发展。汽车后服务市场是指从汽车售出到最终报废过程中,厂商根据车主后续需求,围绕汽车使用、维护、置换和汽车金融等方面提供的各种产品服务,主要包括:二手车交易、汽车维修。

The optimization of allocation for emergency resource of Urban rail under network conditions

After Anglicizing emergency resource allocation problem of Zhengzhou rail network, a dynamic programming algorithm is proposed, then make model for the problem, meanwhile searching the optimal solution for allocation of emergency resources with improved dynamic programming algorithm. The resulting optimal solution is accurate, and can be able to provide good decision support for optimal allocation of emergency resources of Zhengzhou rail transportation under network condition, making rail transport operations much safer.
