动态车辆调度系统的滚动时域调度算法     

贾永基  谷寒雨  席裕庚 《东南大学学报》2005,21(1):92-96

提出了一类特殊的动态车辆调度问题--动态独占性带时间窗口装卸货问题.给出了问题的数学描述,分析了其静态性质,并把问题简化为不对称带时间窗口旅行商问题.提出了求解该动态问题的滚动时域调度算法,通过时域的不断滚动,不仅可以跟踪问题的动态变化,还由于每次滚动只对部分客户进行处理,可以减少问题的求解时间.并分析了算法的3个要素:当前客户窗口、当前客户窗口的调度和滚动策略.测试结果验证了算法在求解动态车辆调度问题中的有效性.  相似文献   

Should Science be Taught in Early Childhood?     

Haim?EshachEmail author  Michael?N.?Fried 《Journal of Science Education and Technology》2005,14(3):315-336

This essay considers the question of why we should teach science to K-2. After initial consideration of two traditional reasons for studying science, six assertions supporting the idea that even small children should be exposed to science are given. These are, in order: (1) Children naturally enjoy observing and thinking about nature. (2) Exposing students to science develops positive attitudes towards science. (3) Early exposure to scientific phenomena leads to better understanding of the scientific concepts studied later in a formal way. (4) The use of scientifically informed language at an early age influences the eventual development of scientific concepts. (5) Children can understand scientific concepts and reason scientifically. (6) Science is an efficient means for developing scientific thinking. Concrete illustrations of some of the ideas discussed in this essay, particularly, how language and prior knowledge may influence the development of scientific concepts, are then provided. The essay concludes by emphasizing that there is a window of opportunity that educators should exploit by presenting science as part of the curriculum in both kindergarten and the first years of primary school.  相似文献   

Enhanced teaching and student learning through a simulator-based course in chemical unit operations design     

Nayef Ghasem 《European Journal of Engineering Education》2016,41(4):455-467

This paper illustrates a teaching technique used in computer applications in chemical engineering employed for designing various unit operation processes, where the students learn about unit operations by designing them. The aim of the course is not to teach design, but rather to teach the fundamentals and the function of unit operation processes through simulators. A case study presenting the teaching method was evaluated using student surveys and faculty assessments, which were designed to measure the quality and effectiveness of the teaching method. The results of the questionnaire conclusively demonstrate that this method is an extremely efficient way of teaching a simulator-based course. In addition to that, this teaching method can easily be generalised and used in other courses. A student's final mark is determined by a combination of in-class assessments conducted based on cooperative and peer learning, progress tests and a final exam. Results revealed that peer learning can improve the overall quality of student learning and enhance student understanding.  相似文献

对提升高职院校校内实训基地管理运营效率的思考     

申屠江平 《金华职业技术学院学报》2011,11(1):1-5

高职院校校内实训基地普遍存在实训效益不佳、对外服务运营不力、设备利用率不高等问题,其根本原因在于重建轻管、重硬件投入轻软件建设。只有建立统一领导、分级管理的运营机制,打造结构合理、能教善做的实训教学团队,深化校企合作、加强工学结合,才能提高管理运营效率,实现校内实训基地的自我运作、自我建设和自我发展。  相似文献
