简介:摘要:当前,高质量发展已成为提升中国经济发展的重要推手,传统勘察设计行业在新常态经济运行发展中将面临重大机遇与挑战。推进设计院的战略转型升级和转变发展方式,是提高发展质量、实现快速发展的重要课题。结合当前设计院面临的形势和任务,探讨设计院业务推进战略转型升级是提高发展质量、实现企业的愿景目标的基本思路。纵观设计院近些年的转型发展,其自身发展理念转变尤为重要,成功的设计院转型从思维转变到组织调整、到资源能力匹配均不可或缺。
简介:摘要:从绩效管理的相关概念、常用的工具方法、体系构建等方面进行简要研究,为设计院绩效管理提供经验,提升设计院的绩效管理水平,努力实现企业战略目标,也为其他企业的绩效管理提供借鉴意义。
简介:利用江淮梅雨区66个测站1960—2014年逐日降水数据和同期NCEP/NCAR再分析资料,基于多个极端降水指数,通过趋势分析、EOF分析和合成分析等手段,探究该区夏季极端降水事件的时空变化特征及影响因素。结果表明:(1)夏季极端降水指数以上升为主,显著上升区主要位于东部。(2)夏季极端降水指数第一特征向量呈全“+”分布形态,北部地区更强,第二特征向量呈“西北+东南-”分布形态;第一模态时间系数呈上升趋势,第二模态时间系数变化趋势不明显。(3)在强(弱)夏季极端降水典型年,西太平洋副热带高压位置偏西(东),中纬度地区表现出经(纬)向型环流分布特征,利于(不利于)江淮地区极端降水发生;同时,对流层中、低层上升运动增强(中层气流辐散增强),水汽通量增强、辐合(减弱、辐散),因此,梅雨区极端降水异常增强(减弱)。
