Partial dominance in branch-price-and-cut algorithms for vehicle routing and scheduling problems with a single-segment tradeoff many variants of vehicle routing and scheduling problems solved by a branch-price-and-cut (BPC) algorithm, the pricing subproblem is an elementary shortest...

Branch-and-cut and Branch-and-Cut-and-Price Algorithms for Solving Vehicle Routing Problems This paper presents a branch-and-cut-and-price algorithm for the vehicle routing problem with time windows. The standard Dantzig-Wolfe decomposition of the arc flow formulation leads to a set partitioning ...
evolutionary algorithms [9] and enumerative schemes, both LP [7, 31] and non-LP based [20, 29]. However, for CSP where the right-hand side is large, LP-based exact methods have been more effective. In the last years many efforts have been successful to solve CSP exactly by an...
In order to evaluate the proposed distribution policies, Archetti et al. (2016) carried out worst-case as well as experimental analyses. In particular, they devised exact and heuristic algorithms. The tests were run on 64 small instances, with 15 customers and up to three commodities, 80 mid...
The experiments compare the new algorithms among themselves and also against the best algorithms currently available in the literature. As an outcome of them, one of the new algorithms stands out on top. 展开 关键词: Degree Constrained Spanning Tree Branch-and-cut Branch-and-cut-and-price ...
Branch-price-and-cut algorithms for the pickup and delivery problem with time windows and multiple stacks This paper proposes models and algorithms for the pickup and delivery vehicle routing problem with time windows and multiple stacks. Each stack is rear-loa... M Cherkesly,G Desaulniers,S...

Capacitated vehicle routing problems are widely studied combinatorial optimization problems, and branch-and-cut-and-price algorithms can solve instances harder than ever before. These models, however, neglect that demands volumes are often not known with precision when planning the vehicle routes, thus ...
Finally, we compare our BPC algorithm with algorithms from the literature in Section 3.4. We Conclusions In this work, we have presented a new branch-price-and-cut (BPC) algorithm for the solution of different variants of the capacitated multiple vehicle traveling purchaser problem (MVTPP) with...
