Derivation of Eqs. (7.12a)(7.12c) for HSDT model

Eqs. (7.11a)(7.11d), which is the LP problem of finding T = {tpq} that maximizes link load on (i, j), is represented with a matrix expression by

where

N is the number of nodes. t is an NN × 1 matrix. Xij is an NN × 1 matrix. A is a (2N + 2NN) × NN matrix. C is a (2N + 2NN) × 1 matrix.

The dual of the LP problem represented by Eqs. (B.1a)(B.2d) for(i, j) is

where

zij is a (2N + 2NN) ...
