尽管城市交通电气化快速发展,但电池电动公交车(EB)车队的系统规划和管理进展却较为落后。本研究首先综述了影响电池电动系统的基本问题,包括充电站部署、电池尺寸、公交车调度和生命周期分析。目前,EB系统的规划和运行是按顺序进行的,公交车调度是在公交车队和基础设施部署完毕后进行的,这导致了资源利用率低和资源浪费。对此,本文提出了混合整数规划模型整合充电站部署和公交车队管理,以尽可能低的生命周期成本(LCC),包括所有权、运营、维护和排放费用,缩小最佳规划与运营之间的差距。引入了分支定价算法,以减少寻找最佳解决方案所需的计算工作量。本研究还通过分析真实案
例,与目前的公交运营策略和充电站布局相比,一条公交线路的LCC优化后可显著降低30.4%。提出的方法不仅可以进行生命周期分析,还可以为交通部门和运营商提供可靠的充电桩部署及单线和多线的公交调度计划,这两者都是未来具有高电气化普及率的交通系统中决策支持的关键要求,此研究也有助于推动可持续交通的发展。

针对CAN总线中消息在固定优先级调度(FPS)算法下传输不可预知、低优先级消息容易被阻塞的问题,提出了一种基于时间触发机制的固定优先级调度(TT-FPS)算法,给出了最糟糕响应时间的计算方法。然后以纯电动汽车消息系统为例进行了TT-FPS的性能分析,验证了TT-FPS 较FPS有更好的性能。

Qualitative analysis of direction of public hospital reforms in China

Reforms in public hospitals are among the most important improvements in China’s health care system over the last two decades. However, the reforms that should be implemented in public hospitals are unclear. Thus, a feasible direction of reforms in Chinese public hospitals is suggested and reliable policy suggestions are provided for the government to reform public hospitals. The data used in this study were mainly derived from a qualitative study. Focus group discussions and in-depth interviews were conducted in Shanghai, Guangdong, and Gansu between May and December 2014. Government funding accounted for approximately eight percent of the total annual revenue of public hospitals in China, and the insufficient government subsidy considerably affects the operation mechanism of public hospitals. However, solely increasing this subsidy cannot address the inappropriate incentives of public hospitals in China. The most crucial step in setting the direction of reforms in public hospitals in China is transforming inappropriate incentives by implementing a new evaluation index system for directors and physicians in public hospitals.
