WebLinear Programming and Extensions - George Bernard Dantzig 1998 In real-world problems related to finance, business, and management, mathematicians and economists frequently encounter optimization problems. First published in 1963, this classic work looks at a wealth of examples and develops linear programming methods for solutions. Webcoordinated sequence of smaller LP problems - the Decomposition Principle of dantzig & Wolfe, 1960 - is certainly a key concept of Linear Programming. In addition to the Decomposition Principle, a particular decomposition procedure was proposed by Dantzig & Wolfe, but as a computational technique this has enjoyed a more mixed success.

Webwith Dantzig-Wolfe decomposition, the column generation algorithm is a commonly-used method for solving multi-commodity flow problem. In this section, the steps of col-umn generation are introduced. 2.2.1 Preparation: Dantzig-Wolfe decomposition In order to solve MCFP with column generation, we need to use Dantzig-Wolfe decomposition first.
