The two-machine flowshop environment with sequence-independent setup times has been intensely investigated both from theoretical and practical perspectives in the scheduling literature. Nevertheless, very scant attention has been devoted to deriving effective lower bounding strategies. In this...

In this paper, new repair and rescheduling algorithms are developed for the unrelated parallel machine environment. The introduced rules and algorithms are used to handle different rates of breakdowns and delays and are evaluated based on several performance measures to ensure the optimisation...

This paper examines the Aircraft Sequencing Problem (ASP) over multiple runways, under mixed mode operations with the objective of minimizing the total weighted tardiness of aircraft landings and departures simultaneously. The ASP can be modeled as a parallel machine scheduling problem with...
