Flow pack facets of the single node fixed-charge flow polytope
i∈N yi ≤ b, yi ≤ uixi ∀i ∈ N}, where variable yi is the flow on arc i with capacity ui, xi is a binary variable that indicates whether arc i is open or closed, and N = N ∪N. The single node fixed–charge flow model is interesting not only because it is a relaxation of the fixed–charge network flow problem, but also because it is possible to derive relaxations of the form S of a general MBIP prob...
متن کاملInitialization of the Benders master problem using valid inequalities applied to fixed-charge network problems
Network problems concern the selection of arcs in a graph in order to satisfy, at minimum cost, some flow requirements, usually expressed in the form of node–node pair demands. Benders decomposition methods, based on the idea of partitioning of the initial problem to two sub-problems and on the generation of cuts, have been successfully applied to many of these problems. This paper presents a n...
متن کاملPath Cover and Path Pack Inequalities for the Capacitated Fixed-Charge Network Flow Problem
Capacitated fixed-charge network flows are used to model a variety of problems in telecommunication, facility location, production planning and supply chain management. In this paper, we investigate capacitated path substructures and derive strong and easy-to-compute path cover and path pack inequalities. These inequalities are based on an explicit characterization of the submodular inequalitie...
متن کاملThree-partition flow cover inequalities for constant capacity fixed-charge network flow problems
Flow cover inequalities are among the most effective valid inequalities for capacitated fixed-charge network flow problems. These valid inequalities are based on implications for the flow quantity on the cut arcs of a two-partitioning of the network, depending on whether some of the cut arcs are open or closed. As the implications are only on the cut arcs, flow cover inequalities can be obtaine...
متن کاملSolving the Fixed Charge Transportation Problem by New Heuristic Approach
The fixed charge transportation problem (FCTP) is a deployment of the classical transportation problem in which a fixed cost is incurred, independent of the amount transported, along with a variable cost that is proportional to the amount shipped. Since the problem is considered as an NP-hard, the computational time grows exponentially as the size of the problem increases. In this pape...
