A new mixed-integer programming formulation for the problem is provided, and a solution algorithm is developed on the basis of the column generation scheme to exactly solve the problem for the first time. The pricing subproblem is solved by a bidirectional labelling algorithm, and the master ...
synchronizationbranch-and-price-and-cutIn this article, we propose a branch‐and‐price‐and‐cut (BPC) algorithm to exactly solve the manpower routing problem with synchronization constraints (MRPSC). Compared with the classical vehicle routing problems (VRPs), the defining characteristic of the ...

general-purpose cutting planes; a cutting plane algorithm for CSP was tested in [28, 2]. A pure cutting plane approach appeared almost equally effective to branch-and-price for CSP with a single stock length [2]. In 2CP, the objective function has its values among integer combinations ...
In that algorithm, columns correspond to possible salesperson day trips; subtour elimination cuts, 2-path cuts, and limited-memory subset row cuts are separated. Computational results show that many medium-sized instances, having up to 75 clients and 20 hotels, can be solved to optimality, as ...
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...

The problem is solved by means of a branch-and-price algorithm. The DSDVRPTW can indirectly model the C-SDVRP by defining the set of orders to associate with a customer as the set of all possibles subsets of commodities to deliver to him. In this paper, we focus on the exact solution...
