【摘要】：我国铁路集装箱运输正处于蓬勃发展阶段,“一带一路”战略构想的提出为集装箱国际化运输业务带来了新的机遇和挑战。铁路集装箱中心站作为运输网络上的重要节点,其内部作业资源的合理调度对于提高中心站作业效率,保障整个运输网络的服务水平有着重要作用。本文在此背景下对铁路集装箱中心站轨道门吊、集卡和正面吊作业设备调度过程展开优化研究。主要研究内容如下:(1)为明确研究目标,首先介绍集装箱中心站的功能布局与作业流程,对集装箱中心站的资源配置情况进行分析,进而确定本文主要研究对象为“轨道门吊-集卡-正面吊”方案;针对本文研究方案,分析了其作业过程中待优化环节,明确本文的研究范围,即围绕轨道门吊、集卡、正面吊三种作业设备,对其作业顺序及设备间的衔接关系展开优化。(2)针对“轨道门吊-集卡-正面吊”装卸工艺方案,首先分析其独立装卸作业模式和混合装卸作业模式的区别,进而明确本文研究内容为作业过程更加复杂的混合装卸作业模式。在此基础上,以集装箱作业过程中的作业时间间隔、作业相互接续关系、作业设备使用条件为约束,建立“轨道门吊-集卡-正面吊”调度模型,研究在一定设备数量条件下,如何合理实现集装箱装卸任务的作业完成时间最小化。(3)针对上述模型特点设计遗传算法,并结合实际情况设计算例对模型和算法的可行性进行验证。通过算例求解出优化后的作业完成时间和设备的使用方案;为进一步验证优化效果,在任务量不变的情况下借鉴前人研究,求解出独立装卸模式下作业完成时间,并对比两种模式下的作业时间结果,分析得出混合装卸模式的作业完成时间更优的结论,进一步证明了模型和算法的有效性。
[Abstract]:China's railway container transportation is in a vigorous stage of development. The strategic concept of "Belt and Road" brings new opportunities and challenges to the international container transport business. As an important node in the transportation network, the rational scheduling of the internal operational resources of the railway container central station plays an important role in improving the operation efficiency of the central station and ensuring the service level of the whole transportation network. In this context, the optimization research on the dispatching process of railway container central station rail gantry crane, collecting card and front crane equipment is carried out in this paper. The main research contents are as follows: (1) in order to clear the research goal, the function layout and operation flow of container central station are introduced, and the resource allocation of container central station is analyzed. Furthermore, it is determined that the main research object of this paper is the project of "track gantry crane-collecting card-front crane"; In view of the research scheme of this paper, this paper analyzes the links to be optimized in the process of operation, and clarifies the research scope of this paper, that is, three kinds of working equipment around the track door crane, the collecting card and the front crane. The order of operation and the connection between equipments are optimized. (2) in view of the loading and unloading process scheme of "track door hoisting, collecting card and front crane", the difference between the independent loading and unloading operation mode and the mixed loading and unloading operation mode is analyzed at first. Furthermore, it is clear that the research content of this paper is the mixed loading and unloading mode which is more complicated in the operation process. On this basis, taking the operation time interval in the container operation process, the relationship between the operations and the operating equipment as constraints, the scheduling model of "track door hoisting, collecting card and front crane" is established, and the scheduling model is studied under the condition of certain number of equipments. How to minimize the completion time of container loading and unloading task reasonably. (3) the genetic algorithm is designed according to the characteristics of the above model, and the feasibility of the model and algorithm is verified by a practical example. An example is given to solve the optimized job completion time and the usage scheme of the equipment. In order to further verify the optimization effect, the completion time of the operation in the independent loading and unloading mode is solved with reference to the previous research under the condition of constant task quantity, and the results of the operation time under the two modes are compared. The conclusion that the completion time of the mixed loading and unloading mode is better is obtained, and the validity of the model and the algorithm is further proved.
