In the so-called weighted Dantzig–Wolfe decomposition algorithm, instead of the optimal solution of the Dantzig–Wolfe master problem a specially weighted average of the previously constructed Lagrangian multipliers and the optimal solution of the master problem is used as Lagrangian multiplier for the...
Dantzig-Wolfe Decomposition Algorithm 1 Solve restricted master with initial basic feasible solution, store π, t 1 , t 2 2 Solve subproblems 1 and 2. If (c T 1 −π T A 1 )x ≥ t 1 and (c T 2 −π T A 2 )x ≥ t 2 terminate with optimal solution: x 1 = j∈ ˜ ...
In this paper a modified Dantzig-Wolfe decomposition algorithm is interpreted as a. decontralized planning process. The main objective is to provide some extensions of the pricing and allocation rules of the original algorithm to make the solution process more efficient. A simple numerical example ...

Dantzig-Wolfe decomposition algorithm. {initialization} Choose initial subsets of variables. while true do 1 The reduced cost of a variable x j is (13) σ j = c j −π T A j where A j is the column of A corresponding to variable x j , and π are the duals. DANTZIG-WOLFE DECOM...
In the following sections, we evaluate the computational efficiency of the Dantzig–Wolfe decomposition algorithm through an empirical complexity study. Without loss of generality, we consider a large-scale block-angular LP problem with p subproblems in its standard formmax∑iciTxisubject to∑iAi...
This chapter presents a formulation for the job shop problem based on Dantzig-Wolfe decomposition with a subproblem for each machine. Each subproblem is a sequencing problem on a single machine with time windows. The formulation is used within an exact algorithm capable of solving problems with obj...
