电动汽车行驶里程短、充电时间长是影响驾驶体验的关键.通过对电网、充电设备进行大规模升级的方法减少充电时间,成本昂贵,因此充分利用现有路网、电网资源,制定智能充电调度策略成为提高驾驶体验的重要手段.考虑到驾驶者对充电时间敏感度的异质性,提出具有差异化的调度策略以满足不同优先级驾驶者的需求.首先,为均衡不同优先级驾驶者的利益,提出一种基于动态截断机制的两优先级队列模型;其次,定义充电站的准入原则,保证高优先级驾驶者对预留桩的使用权及对空闲桩的优先抢占权;然后,提出基于截断机制的双层优化模型CCPQ(charging with cut-off priority queue),在顶层高优先级车辆与充电桩最优匹配的基础上,设计底层低优先级车辆的分配策略优化模型,将最小化低优先级驾驶者的总等待时间构建为凸优化问题;最后,通过仿真验证策略的有效性及优越性.

职业院校数据治理是职业教育治理体系现代化的核心要素。职业院校校本数据治理范式的提出,符合国家职业教育治理体系从宏观建构转向微观规范的政策诉求。职业院校校本数据治理遵循从碎片转向全局的价值逻辑、从孤岛转向共生的过程逻辑、由浅表转向深度的技术逻辑及从适应转向预测的功能逻辑等四重转型逻辑。在实践场域,职业院校校本数据治理存在数据生态失衡与数据架构断点、数据规格泛化与信息离散、数据治理政策缺位与流程迟滞、数据治理偏利取向与效用失准等现实问题。推动职业院校校本数据治理实践范式建构,可从基于国家“智慧大脑”架构的共生共治价值体系建构、基于数据生命周期的数据全链条管理过程机制建构、基于多源异构数据的分层治理技术载体建制、基于师生同频成长支持体系动力设计的功能系统调试四个维度展开。

书院赋是以书院的教学内容、自然地理、哲学思想为描写对象的赋作,中国的书院产生于唐末,兴盛于宋,明清时期广泛普及。特别是宋明年间理学体系的建立,促进了书院赋的发展与繁荣。从两宋至明清,随着科举的完备和推行,八股取士、官学私学的发展,书院赋也逐渐呈现出官学化倾向,明清书院赋的多种形态“学堂赋”“辟雍赋”“郡学赋”“讲学赋”“书舍赋”都展示了儒家教育的主体地位与书院赋的道学情怀。通过对宋元明清书院赋的发展状况进行梳理,特别对由宋至明代,书院因科举而理学兴盛的特点进行分析,探究宋代书院赋官学化之思想基础——儒家理学精神的产生,进而对明清书院赋的官学化倾向有较为全面的认知——赋作走向格律化,官学倾向带来的郡学赋的兴盛,最后总结评价宋明以来书院赋官学化的意义与影响。主要从书院赋官学化倾向为立足点,研究书院在宋明时期的特征与新变,通过论述对于赋作的官学化体系有初步的探索。
