Anders Ivarsen PhD,Jesper Hjortdal DMSc polytope associated with this formulation, introduce new valid inequalities and design separation algorithms. The other formulation is based on flows and has a polynomial number of constraints and variables. Computational experiments show that our formulations achieve better results than the other formulations presented in the literature.作者: 卷發(fā) 時(shí)間: 2025-3-22 05:33 作者: 同步信息 時(shí)間: 2025-3-22 10:33 作者: Hypopnea 時(shí)間: 2025-3-22 13:59

Hoon Jai Chun,Sang-Yong Seol,Joo Young Chostudied. Second we consider generalized precedence constraints, which include, e.g., deadline constraints. Altogether this leads to a more realistic rescheduling problem. The main result is to show that the problem is polynomial. We discuss how to benefit from the polynomiality result in a machine scheduling environment.作者: 疼死我了 時(shí)間: 2025-3-25 15:34
