Partial dominance in branch-price-and-cut algorithms for vehicle routing and scheduling problems with a single-segment tradeoff For many variants of vehicle routing and scheduling problems solved by a branch-price-and-cut (BPC) algorithm, the pricing subproblem is an elementary shor... S Faldum,...
To address the problem, we develop an exact branch-price-and-cut algorithm based on the set-partitioning formulation. An effective bidirectional labeling algorithm is proposed to deal with the pricing problem. Numerical studies have verified that the proposed algorithm can obtain the exact optimal ...
Branch-price-and-cut is a leading methodology for solving various vehicle routing problems (VRPs). For many VRPs, the pricing problem of a branch-price-and-cut algorithm is highly complex and, to alleviate this difficulty, a relaxed pricing problem is used. In this paper, we introduce a ...
今天发现了一个VRP领域的大牛做的PPT,关于Branch and price and cut算法求解传统VRP问题以及VRPTW的。 详细推文可参考公众号往期的介绍。 PPT有92页之多,详细介绍了VRP问题的建模以及算法的各个知识点。 值得分享,大家可以收藏一下,说不定以后能用得上呢。哈哈哈哈! 获取方式在后台回复【BPCVRP】不包括【】即可下...

To date, only heuristic approaches have been proposed for this problem, and even the most efficient optimization solvers cannot find optimal solutions in a reasonable amount of time for instances of moderate size when using the available mathematical formulations. We propose a branch-price-and-cut ...
The travel cost per unit distance is a linear function of the vehicle weight and the customer demand can be fulfilled by multiple vehicles. To solve this problem, we propose a exact branch-and-price-and-cut algorithm, where the pricing subproblem is a resource-constrained elementary least-cost...
