含充电节点的能量感知车辆路由

Energy-aware Vehicle Routing in Networks with Charging Nodes

Tao Wang, Christos G. Cassandras, Sepideh Pourazarm

摘要:

研究了具有能量约束的车辆在至少有一些充电节点的网络中的路径问题。我们希望尽量缩短载具到达目的地的总时间,方法是厘定路缐,以及在载具没有足够能源作整段行程之用的情况下,厘定充电量。对于一个单一的车辆,我们制定了一个混合整数非线性规划(MINLP)的问题,并推导出的最优解的属性,允许它被分解成两个更简单的问题。对于一个多车辆的问题,其中包括交通拥堵的影响,我们使用了类似的方法,通过分组车辆到子流。我们还提供了一个替代的流量优化配方,导致计算简单的问题解决方案,精度损失最小。数值结果来说明这些方法。

英文摘要:

We study the problem of routing vehicles with energy constraints through a network where there are at least some charging nodes. We seek to minimize the total elapsed time for vehicles to reach their destinations by determining routes as well as recharging amounts when the vehicles do not have adequate energy for the entire journey. For a single vehicle, we formulate a mixed-integer nonlinear programming (MINLP) problem and derive properties of the optimal solution allowing it to be decomposed into two simpler problems. For a multi-vehicle problem, where traffic congestion effects are included, we use a similar approach by grouping vehicles into subflows. We also provide an alternative flow optimization formulation leading to a computationally simpler problem solution with minimal loss in accuracy. Numerical results are included to illustrate these approaches.
