摘要:

本文提出了一种新的路径问题--带向量利润的车辆路径问题。给定一个由节点(仓库/站点)和连接节点的弧组成的网络,该问题确定从仓库出发,访问站点以收集利润,并返回仓库的路线。有多个利益相关者对任务感兴趣,每个站点都与一个向量相关联,该向量的第k个元素代表第k个利益相关者的利润值。问题的目标是最大化最不满意的利益相关者的利润总和,即,总利润值最小的股东。提出了一种基于线性规划松弛和列生成的最大-最小型布线问题的求解方法。两个案例研究-行星表面探索和罗马之旅的情况下-提出了证明所提出的问题制定和解决方法的有效性。

英文摘要:

This paper introduces a new routing problem referred to as the vehicle routing problem with vector profits. Given a network composed of nodes (depot/sites) and arcs connecting the nodes, the problem determines routes that depart from the depot, visit sites to collect profits, and return to the depot. There are multiple stakeholders interested in the mission and each site is associated with a vector whose k-th element represents the profit value for the k-th stakeholder. The objective of the problem is to maximize the profit sum for the least satisfied stakeholder, i.e., the stakeholder with the smallest total profit value. An approach based on the linear programming relaxation and column-generation to solve this max-min type routing problem was developed. Two cases studies - the planetary surface exploration and the Rome tour cases - were presented to demonstrate the effectiveness of the proposed problem formulation and solution methodology.
