Based on EMME/2 Transit Equilibrium Assignment Model Improvement and Algorithm Research
At present, the transit equitment model which had studied is not truly suitable for the urban road networks, thus the model fitting effect is not so well. Therefore, this thesis did systematically research on using the transit equilibrium assignment model in the platform of EMME/2.This thesis analyzes the impedance foundation of the existing equilibrium assignment [...]
Research on the Estimating Connectivity Reliability of Transport Networks
The transport network is one of main object for socio-economic, its stability is directly related to the development of the national economy. However, the operation of transport network is affected by many factors, so that it is caused by the uncertainty. Therefore, in order to better solve the traffic problems, it needs to correct the [...]

The Reliability Evaluation of Large-scale Power Supply System and Voltage Sag Based on the Analytical Method
Because of increasing scale and complexity of electrical system power supply network, new requirements for service ability of electrical system are put forward. Over the past few decades, on the topic of service ability of electrical system analysis the research on power generation and transmission system reliability is attached importance and service ability is neglect, [...]
The Study on Fiber Bragg Grating Measurement System Applied in Transmission Line Icing Monitoring
Great ice on transmission lines will reduce the economic benefit and stability of electrical power systems. In this paper, a new detection system based on Fiber Bragg Grating (FBG) is proposed to monitor the icing on transmission lines.At first, several FBGS are used together to eliminate the influence of the nonlinearity of the F-P filter [...]
The Research of Parameters’ Identification for Vector Control System of Induction Motor
Vector control system of induction motor is increasingly being used in AC variable frequency system for its excellent dynamic performance. Vector control system very sensitive to parameter changes and with the aging of the motor and the surrounding environment changes, there is a big difference between the actual motor parameters and given parameters. With the [...]
Uncertain Cross Docking Scheduling: Modles and Algorithms
This paper studies car factory inbound uncertain cross docking scheduling problem. Inbound logistics is an important component of the lean production system. It is also known to be the most complex logistics service that needs advanced technology. In cross docking, distribution center only receive and send materials, with few materials in store. Cross docking can [...]
Research on the Automobile Engine Electronic Throttle Control System
As technology advances and the development of automobile industry developed rapidly. In two thousand and eight, China’s automobile output reached fifty one million, nine hundred and thirty thousand. It surpasses the United States and ranks second in the world after Japan. In two thousand and nine, China’s automobile output reached one hundred and thirty seven [...]
The Optimization of Train’s Dispatching and Decesion-making Based on Passenger Station
There are many unreliable factors and events that affect train’s punctual running in the passenger station. At the same time, the passenger station is the important place where we can effeciently improve the reliability of trains running on schedule. From the quality of transport service and passenger’s satification, the research of optimal dispatch on delaying [...]
Study on Integrated Flexible Scheduling with Deferred Constraint
There is a problem in study of integrated flexible scheduling currently, which is that these studies just consider situation that there is sequential constraint among workpieces, but ignore situation that there is deferred constraint among workpieces. In fact, there is deferred constraint problem in practical production. If it is ignored, the manufacturing plan will not [...]
