We research the cooperation optimization problem of assigning locomotives and scheduling trains in single-track railway system. To solve the considered problem, we develop a high-efficient cooperation optimization approach which includes a well-designed locomotive assignment algorithm. We conduct extensive case studies to demonstrate the effectiveness of the proposed cooperation optimization approach...
It is meaningful to discover valuable relationships in big data. The maximal information coefficient (MIC), a new measure of dependence of relationships, was proposed by Reshef et al. in 2011, and an approximate algorithm was designed. But the algorithm designed by Reshef et al. (2011) can only calculate the MIC of two-variable relationships. In this paper, an algorithm (BKM-MIC) is proposed. To our...
The optimal adjustment problem for high speed passenger train operations is considered in this paper. The problem is formulated as 0-1 integer programming model to get the optimal organization of train operations. In addition, a high computation speed heuristic algorithm is proposed in order to get a near optimal solution for the problem.
The aim of the train timetable problem is to determine arrival and departure times at each station so that no collisions will happen between different trains and the resources can be utilized effectively. Due to uncertainty of real systems, train timetables have to be made under an uncertain environment under most circumstances. This paper mainly investigates a passenger train timetable problem with...
