Abstract

In this article, we study a two-parallel machine's early-tardy scheduling problem where some jobs need to be processed by one machine, while the others have to be processed by both machines simultaneously. The objective is to minimize the total earliness and tardiness penalties. Some optimality properties are derived, and then a heuristic method that can find approximate solutions efficiently is proposed. The method can solve 1000-job problems very quickly as the simulation results show.
