A Lagrangian relaxation approach to large-scale flow interception problems

Gzara, Fatma; Erkut, Erhan - In: European Journal of Operational Research 198 (2009) 2, pp. 405-411

The paper presents a tight Lagrangian bound and an efficient dual heuristic for the flow interception problem. The proposed Lagrangian relaxation decomposes the problem into two subproblems that are easy to solve. Information from one of the subproblems is used within a dual heuristic to...
