Solving the Uncapacitated Fixed-Charge Network Flow with Metaheuristics

چکیده

The Uncapacitated Fixed-charge Network Flow (UFNF) problem is an instance of the broader class of Network Design (ND) problems. Let G = (S,A) be a digraph where S is the set of nodes and A is the set of arcs. Each arc (i, j) is associated with two costs: a fixed cost ci,j for selecting (i, j) and a variable cost di,j for routing flow on (i, j). The problem is to find a set of arcs that allow a supply node to send resources to a set of demand nodes, such that the sum of structural (ci,j) and operational (di,j) costs is minimized.

Solving 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...

Solving to optimality the uncapacitated fixed-charge network flow problem

Given a directed network, the uncapacitated fixed-charge network flow problem is to find a minimum-cost arc combination that provides flows from the supply nodes to the demand nodes. Associated with all arcs are two costs: the fixed charge of using the arc and the variable cost depending on the amount of flow the arc actually carries. This generic model has applications for problems of distribu...

A branch-and-cut algorithm for the single-commodity, uncapacitated, fixed-charge network flow problem

We present a branch-and-cut algorithm to solve the single commodity uncapacitated fixed charge network flow problem, which includes the Steiner tree problem, uncapacitated lot-sizing problems, and the fixed charge transportation problem as special cases. The cuts used are simple dicut inequalities and their variants. A crucial problem when separating these inequalities is to find the right cut ...

The Uncapacitated Time-Space Fixed-Charge Network Flow Problem: An Empirical Investigation of Procedures for Arc Capacity Assignment

The nodes and arcs of a network configuration replicated over time is a common structure found in many applications, particularly in the area of logistics. A common cost structure for flows in arcs for such problems involves both a fixed and variable cost. Combining the two concepts results in the uncapacitated time-space fixed-charge network flow problem. These problems can be modeled as mixed...
