摘要:

带时间窗的多车辆覆盖旅游问题(MCTPTW)的目的是构建一组最大覆盖范围的路线车队,服务(观察)的第二组站点给定一个固定的时间表,覆盖要求和能源限制。该问题被表述为一个混合整数二阶锥规划(MISOCP)模型,是一个扩展的多覆盖旅游问题和车辆路径问题的时间窗下的能量约束。此外,我们研究了一个特殊的情况下,所提出的模型和开发的标记算法来解决其拉格朗日松弛问题,它利用了组合结构所表现出的最优解的拉格朗日松弛。

英文摘要:

The multi-vehicle covering tour problem with time windows (MCTPTW) aims to construct a set of maximal coverage routes for a fleet of vehicles that serve (observe) a secondary set of sites given a fixed time schedule, coverage requirements, and energy restrictions. The problem is formulated as a mixed-integer second-order cone programming (MISOCP) model and is an extension of both the multi-covering tour problem and the vehicle routing problem with time windows under energy constraints. Further, we study a special case of the proposed model and develop a labeling algorithm to solve its Lagrangian relaxation problem, which exploits the combinatorial structure exhibited by an optimal solution to the Lagrangian relaxation.
