WebDantzig-Wolfe decomposition is a method for solving large LP problems. The model implementation shows the following features: iterative sequence of concurrent solving of … WebIn , a Mul-CFP model with complementary constraints was constructed and the Dantzig–Wolfe decomposition method was proposed to solve the model. In [ 12 ], the rolling stock scheduling problem was also transformed into a Mul-CFP to construct the model, which was solved using the branch-price algorithm, and the use of Pareto …
