Fractional Routing on Pairs of Failuredisjoint Paths
(2014) In Discrete Applied Mathematics 164. p.4760 Abstract
 Given a set of commodities and a network where some arcs can fail while others are reliable, we consider a routing problem with respect to a survivability requirement that each commodity can be split among pairs of failuredisjoint paths. Two paths p and p′ form a pair of failuredisjoint paths if they share only reliable arcs. The same flow is sent over p and p′, but the flow sent on a common reliable arc is not doubled.
We present a compact linear formulation of the problem. Also three noncompact formulations solvable by column generation are introduced. In the first formulation, the generated columns correspond to pairs of failuredisjoint paths, while in the second formulation the generated columns correspond to...

Two paths p and p′ form a pair of failuredisjoint paths if they share only reliable arcs. The same flow is sent over p and p′, but the flow sent on a common reliable arc is not doubled.
We present a compact linear formulation of the problem. Also three noncompact formulations solvable by column generation are introduced. In the first formulation, the generated columns correspond to pairs of failuredisjoint paths, while in the second formulation the generated columns correspond to simple paths. The third formulation is solved by generating pairs of arcdisjoint paths. All formulations are compared numerically. On top of that we study some generalizations and some special cases of the problem of computing a shortest pair of failuredisjoint paths. One of these generalizations is equivalent to a singlecommodity capacitated network design problem. (Less)
