26Zhengzhou Tiamaes Technology Co.,LtdIntelligent Chain Scheduling Technology based on tabu search
and dynamic programming algorithm
Efficient bus scheduling is an important part in public transportation operation management to solve the problem of urban traffic congestion. For nearly half a century, most of Chinese public transportation companies have adopted a driver-vehicle binding scheduling mode. Driver-vehicle binding means that one driver can only run one vehicle. The advantages of this model are convenient for business management and division of responsibilities, but the disadvantages are also quite obvious. The main reasons are that the driver’s labor efficiency is low and the resources required by the public bus company are also relatively large. Intelligent chain scheduling technology is mainly used to solve the Single Deport-Single Line-Vehicle Scheduling Problem (SD-SL-VSP) and Single Deport-Multi Line-Vehicle Scheduling Problem (SD-ML-VSP). This technology breaks the original working mode of order scheduling of public transportation companies and adopts a more efficient scheduling strategy, that is, the vehicles returning to the home area first are arranged at the nearest departure point to perform the next tasks. At the same time, this technology is mainly aimed at the domestic bus driver scheduling problem under the "driver-vehicle binding" mode. At the same time, considering the cost of vehicles and drivers, the scientific model algorithm, namely the greedy tabu search algorithm, is used to find the smallest number of vehicles and meet the scheduling plan. This product can balance the relationship between the vehicle and the driver on the premise of saving resources to a certain extent, that is, reducing the resources of the enterprise on the basis of effectively improving the labor efficiency of the driver.

32Beijing Zhiyuan CompanyDevelopment of Rigid Conductor Line for High-speed Operation
The development of power electronics has made it possible to use inverters for trains of electric railways. Power is supplied to trains from contact lines on the ground through the pantographs mounted on trains. Therefore, it is necessary to adopt a contact line system that will limit contact loss within the allowable limits for inverters. In addition, high-speed railways of China tend to be constructed in tunnel sections in recent years. When compared with catenary systems, rigid conductor line systems feature a simple structure and easy maintenance. It also saves tunnel Construction costs. Since conventional rigid conductor lines do not have elasticity against pantographs in current collection. However, the current collecting performance depends on its pantograph compliance characteristics and the unevenness of its contact surface. This makes it difficult to cope with train operation over 160 km/h. To use rigid conductor line systems for train operation over 160 km/h, therefore, we have developed a new rigid conductor line. Running tests have proved that the new rigid conductor line ensures current collection up to 200 km/h and is applicable to train operation even at higher speed due to its superb performance of current collection.
