Witryna17 lut 2024 · We develop two decomposition methods that are computationally faster than solving the model directly via a state-of-the-art solver. We present both some theoretical results for our algorithms and numerical results for the evaluation of the model and algorithms. Witryna2 sie 2024 · First, we compare the constraint programming (CP) model with the mixed-integer programming (MIP) model for F-JSSPs. Second, we exploit the decomposable structure within the models and develop an efficient CP–logic-based Benders decomposition (CP-LBBD) technique that combines the complementary strengths of …
Propagating logic-based Benders’ decomposition approaches …
Witryna17 lut 2024 · We decompose the original problem into a master problem, where the configurations are determined, and a subproblem, where the production amounts are determined. This allows us to apply the LBBD technique to solve the problem using a standard LBBD implementation and a branch-and-check algorithm. Witryna15 cze 2016 · A 3-level logic-based Benders’ decomposition solves the problem efficiently. • The approach is vastly superior to the corresponding 2-level decomposition. • Strengthening cuts by breaking symmetries, and strengthening each master, is critical.

Witryna17 cze 2024 · Logic-based Benders decomposition (LBBD) [9, 12] is an extension of Benders decomposition [2, 8] in the sense that it allows for a more general type of optimisation problem as a subproblem.In the classical Benders decomposition scheme [], developed for mixed integer programs (MIPs), the subproblem obtained after fixing … Witrynatechniques in logic-based Benders’ decomposition Aigerim Saken1, Emil Karlsson 2;3, Stephen J.
