交通运输科技创新驱动发展关键制约及发展策略研究

为深入分析我国交通运输科技创新发展面临的关键制约问题，提出创新驱动发展的战略举措，对我国交通运输科技创新在体制机制、技术研发、能力建设及成果转化等方面存在的问题进行了分析，研究了新时期交通运输科技创新面临的经济、人口、社会、气候环境、国际政治等方面的形势需求，提出了我国交通运输科技创新驱动发展的政策措施建议。研究认为，我国交通运输科技创新驱动发展的根本制约在于技术研发自主程度不足、创新动力活力不足，科技创新成果转化链条不畅；新时期，我国交通运输科技创新需加强统筹谋划，强化顶层设计，加强科技研发，增强自主创新能力，进一步深化体制机制改革，激发创新活力。     

Optimum arrangement of braces in jacket platform based on strength and ductility

Nonlinear behavior of jacket platforms is important in both design and rehabilitation issues that depends on the bracing arrangement. Both ductility and strength of the structures derived from pushover analysis are highly related to configuration of the braces. Considering a suitable criterion such as constant weight or constant stiffness and period of the structure in all arrangement cases, one can compare the capacity curves and find the best configuration. In this paper a simple logical method for investigating the strength and ductility of the jacket structure is presented, it is shown that global geometry and configuration of the braces are very important and effective in both strength and ductility parameters. Three parameters, normalized strength, normalized ductility and a combination of these two parameters are defined in order to have an engineering and practical index for comparing the results. At the end of the numerical discussion, the optimum configuration can be found. Such an investigation is very important in the initial design stage. Also, in assessment of existing platforms, it is very important to find the reliable strength and ductility of the structure. Such a study gives a deep view of this issue as well.     

基于蚁群算法的维修保障资源应急调度研究

在保障资源损毁后,将现有保障资源整合成机动保障小组,按照一定的机动路线巡回实施支援保障,可以最大限度的节省现存保障资源,提高保障效能。实施机动巡回的资源调度,需要确定机动保障小组的数量以及机动的路线,这类问题可归结为带约束条件的组合优化问题。应用蚁群算法建立了机动巡回保障优化数学模型,给出了算法的实现步骤。案例结果表明,该算法可以快速、有效求得巡回保障的优化解,得到巡回保障过程中的较优方案。     

Automated tuning of ITS management and control systems: Results from real-life experiments

The design and deployment of the majority of Management and Control Systems (MCS) for ITS involves a tedious, effort- and time-consuming manual tuning and calibration procedure not only during the initial design and deployment of the ITS but, in most cases, during its whole lifetime. Recently, we have developed and evaluated, both by means of theoretical analysis and extensive simulation experiments, a new methodology which fully automatically takes over the manual tuning and calibration procedure. Most importantly, this new methodology, called Adaptive Fine-Tuning (AFT), achieves to improve the performance of the system and compensate the effect of the continuous changes of its behavior that may be due to either internal or external factors. In this paper, we report results of implementing AFT to a real-life ITS MCS. More precisely, this paper reports and analyzes the results from implementing AFT to an urban traffic signal control application. The results from AFT real-life application demonstrate that it is capable of significantly improving the performance of the system in a safe and robust manner. Moreover, the real-life results exhibit the capability of AFT to efficiently adapt and compensate in cases of changes in the system behavior, even if these changes are significant.     

论员工的绩效薪酬与正向激励

谋求最高劳动生产率是科学管理的根本目的,为了充分调动员工创造价值的主动性和积极性,绩效薪酬管理的重要性在企业管理中日益凸显。为了最大限度地激发员工积极性,科学、可行、合理、公正的绩效考核是有效的管理手段和管理模式。但目前,在相当多的企业中,绩效考核并未达到预期效果,不合理的考核方案甚至可能激起劳资双方的对立情绪或引发员工之间的不当竞争。本文针对此类情况,分析普遍存在的问题并提出了优化对策及非物质激励的改进方案。
