We study a deterministic container transportation problem, jointly optimizing the berth allocation, quay crane assignment and yard storage allocation at container ports. The problem is formulated as an integer program to coordinate the decisions. To solve this large-scale problem, we then transform it into a set partitioning formulation, and provide a framework of branch-and-price algorithm.
In this paper, the four-point bending beam fatigue test control system was modified after analyzing the factors affecting the accuracy of test results. Subsequently, a fractional factorial experimental design method named “uniform design” was applied on the development of laboratory asphalt mixture fatigue prediction model. The regression models expressing the relationships between the influence factors...
The distributions of some random variables of value of travel time data are quite complicated and difficult to determine by using ordinary statistical models. Two maximum entropy functions are borrowed to describe value-of-time (VOT) distributions from different sample size. The traditional VOT-based mode split model is improved by the use of maximum entropy principle. A new algorithm is proposed...
