多车辆最大利润路径问题

Maximum-Profit Routing Problem with Multiple Vehicles per Site

Bogdan Armaselu

摘要:

我们考虑的最大利润路由问题(MPRP),在\cite{Armaselu-arXiv-2016, Armaselu-PETRA},其中的目标是最大限度地提高总利润的皮卡路由问题的变种。原来的MPRP限制车辆访问一个网站最多一次。在本文中,我们认为MPRP的扩展,其中一个网站可能会被访问的车辆多次。具体来说,我们考虑两个版本:一个是在每个站点拾取的数量是恒定的时间(MPRP-M),一个是随时间变化的供应量,随时间线性增加(MPRP-VS)。对于这些版本中的每一个,我们提出了一个常数因子多项式时间近似计划。

英文摘要:

We consider the Maximum-Profit Routing Problem (MPRP), a variant of pick-up routing problem introduced in \cite{Armaselu-arXiv-2016, Armaselu-PETRA}, in which the goal is to maximize total profit. The original MPRP restricts vehicles to visit a site at most once. In this paper, we consider extensions of MPRP, in which a site may be visited by a vehicle multiple times. Specifically, we consider two versions: one in which the quantity to be picked up at each site is constant in time (MPRP-M), and one with time-varying supplied quantities, which increase linearly in time (MPRP-VS). For each of these versions, we come up with a constant-factor polynomial-time approximaltion scheme.
