Engineering logistics is a very important part of modern logistics. It can effectively solve the material transportation problems appeared in the construction of engineering projects and supporting and other aspects of some large-scale conferences. The characteristics of engineering logistics are high risk, timeliness and one-time completion of the project. In the process of its transportation and loading, there is a constant need for special equipment and the cooperation between several logistics enterprises which can offer different modes of transportation. Equipment dismantling, moving, packing, encasing, binding, customs clearance, sea transportation, air transportation, land transportation, unpacking and installation all belong to the service scope of engineering logistics. Because of its large scale, complex structure, wide range of design and strong uncertainty, engineering logistics has become a complex system engineering. In the process of its implementation, it is necessary to combine the theory of system engineering with the theory of logistics system planning, control and management to select the transportation scheme which should have good adaptability to deal with the uncertain factors appeared in the logistics chains.

工程物流是现代物流中很重要的组成部分,它能够很好的解决工程项目建设的物资运输以及一些大型会议、支援等方面的物资运输问题。工程物流的特点是风险性高、时效性强、项目一次性完成;其运输装卸过程中往往需要专用特殊设备,并且需要几种运输方式结合,协同多家物流企业联合操作。设备拆卸、搬移、包装、装箱、绑扎系固、通关、海运、空运、陆运、拆箱、安装等都属于工程物流的服务范围。工程物流因其规模庞大、结构复杂、设计范围广泛、不确定性强等特点,使其成为一项复杂的系统工程。在其实施过程中,需要采用系统工程理论方法结合物流系统规划、控制和管理理论选择运输方案,并要求所采用的运输方案有具有很好的适应性来应对物流链条中的不确定性因素。

After General Secretary Xi Jinping’s important speech on September 18, the ecological protection and high-quality development of the Yellow River Basin has become a national strategy. Local governments at all levels have increased their efforts to protect and develop the Yellow River Basin. The new situation and new requirements presented new challenges to high-quality development of Dongping Lake. In order to strengthen the development of characteristic industries, the development of cultural tourism resources, the construction of urban and rural areas, and the layout of transportation facilities, the stability of the river must be the prerequisite. Ensure the concept of Dongping Lake’s flood prevention and safety barriers, establish the long-term goal of building a “happy river and lake”, and strive to provide Dongping Lake and surrounding areas with “high-quality water resources, healthy water ecology, livable water environment, and advanced water culture” to ensure Dongping lake can store water, drain water, hold floods, supply water, open to navigation, and maintain ecological diversity.

Energy is the material basis for the survival and development of human society, and its importance is self-evident. The increasingly prominent problems of energy shortage and environmental pollution greatly enhance the status of new energy and renewable energy in the field of energy. Solar energy, wind energy, water energy, biomass energy, geothermal energy, marine energy and other energy technologies have also developed rapidly in recent years. In order to overcome the difference between energy supply and energy demand in time and space, it is necessary to use certain methods, through certain media or devices, to directly or indirectly convert one form of energy into another form of energy for storage, and release it when energy is needed. Energy storage technology is a variety of methods to study energy storage.
The traditional power system, which is a real-time balance system formed by a set of generation side variables and a group of power consumption side variables, has the characteristics of instant generation and use. There are generally large peak valley changes in the load on the power side, which brings great pressure to the power generation side and causes many disadvantages of the power system. By using energy storage technology, the surplus power can be stored and sent out at an appropriate time, so as to realize the function of energy storage “regulation, optimization, efficiency increase and protection” in the power system. This can make the power distribution flexible, optimize the system resource allocation, improve the operation efficiency and ensure the stable operation of the system. The development of energy storage technology is to ensure the continuous process of energy utilization. It is very important in human daily life and industrial production, such as electric power industry, new energy vehicles, solar thermal utilization and other fields, and it is of great significance to promote the sustainable development of energy.

能源作为人类社会生存和发展的物质基础,其重要性不言而喻。能源短缺和环境污染等问题的日益突出,极大地提升了新能源和可再生能源在能源领域的地位。太阳能、风能、水能、生物质能、地热能、海洋能等各种能源技术近年来也得到快速发展。为克服能量供应和能量需求在时间和空间上的差别,就需要采用一定的方法,通过一定的介质或装置,将某种形式的能量直接或间接转换成另一种形式的能量储存起来,在需要用能的时候释放出来。研究能量储存的各种方法,即储能技术。
传统模式下的电力系统,即一组发电侧变量和一组用电侧变量所形成的实时平衡的系统,具有即发即用的特点。用电侧负荷普遍存在较大的峰谷变化,给发电侧带来了较大压力,造成了电力系统的诸多弊端。利用储能技术可以把多余的电力储存起来,在适当的时刻再发出去,从而在电力系统中实现储能“调节、优化、增效、保护”的功能,使电能灵活分配,优化系统资源配置,提高运行效率以及保障系统稳定运行等。储能技术的发展,是为了保证能量的利用过程能够连续进行,在人类的日常生活和工业生产等各方面,如电力工业、新能源汽车、太阳能热利用等多个领域,都非常重要,并对促进能源的可持续发展具有重要意义。
