Scheduling jobs with release dates on identical parallel machines by minimizing the total weighted completion time

Kramer, Arthur; Dell'Amico, Mauro; Feillet, Dominique; Iori, Manuel

2020 Mathematics

doi:10.1016/j.cor.2020.105018

Abstract: This paper addresses the problem of scheduling a set of jobs that are released over the time on a set of identical parallel machines, aiming at the minimization of the total weighted completion time. This problem, referred to as $P|r_j|\sum w_jC_j$, is of great importance in practice,...
