    An Optimization Method of High-Speed Railway Rescheduling to Meet Unexpected Large Passenger Flow by Junduo Zhao, Haiying Li, Lingyun Meng, Jianrui Miao

    Published 2022-01-01
    “…In the rapidly changing multimodal transportation market, not only the obligation in providing train services but also the responsibility in helping other transportation modes to meet emergencies are instrumental for maximizing the generalized benefit of railway companies, leading to an increased utilization. This paper proposes an optimization framework, which includes multiple dispatching measures of arranging residual seats, modifying stopping plans, and inserting additional trains, to design a rescheduling operation plan on a high-speed rail corridor to meet the passenger demand of unexpected large passenger flow (ULPF), which is generated from the disruption of other transportation modes. …”

    Minimum latency data aggregation scheduling in MR-MC wireless sensor networks by Jin-bao LI, Meng WANG, Long-jiang GUO

    Published 2014-10-01
    “…The problem of minimum latency data aggregation scheduling in single-radio single-channel wireless sensor networks is a NPC problem and many solutions have been proposed.In multi-radio multi-channel networks,the latency may be lower as a node may receive transmission data from other different nodes simultaneously.It formulates the minimum latency data aggregation scheduling into an optimization problem with joint consider of tree structure,time slot assignment,channel assignment and radio assignment.The problem is divided into constructing data aggregation tree and designing a node schedule subproblems.For each subproblem,heuristic algorithm has been proposed.The simulation results show that the proposed algorithm achieve good performance.…”
