Coordination mechanisms for parallel machine scheduling

Lee, Kangbok; Leung, Joseph Y.-T.; Pinedo, Michael L. - In: European Journal of Operational Research 220 (2012) 2, pp. 305-313

We consider coordination mechanisms for the distributed scheduling of n jobs on m parallel machines, where each agent holding a job selects a machine to process his/her own job. Without a central authority to construct a schedule, each agent acts selfishly to minimize his/her own disutility,...

Open Order Due Date Maintenance in MRP Systems

Penlesky, Richard J.; Berry, William L.; Wemmerlöv, Urban - In: Management Science 35 (1989) 5, pp. 571-584

This paper is concerned with the problem of maintaining open order due dates in job shops that plan and schedule their operations using Material Requirements Planning (MRP) methodology. Two different techniques for dealing with open order due date changes are analyzed using customer service...

VRP12 (vehicle routing problem with distances one and two) with side constraints

Ceranoglu, Ahmet N.; Duman, Ekrem - In: International Journal of Production Economics 144 (2013) 2, pp. 461-467

The problem undertaken in this study is inspired from a real life application. Consider a vehicle routing problem where the distances between the customer locations are either one or two. We name this problem as VRP12 in an analogy for the name TSP12 used for the traveling salesman problem in...

PARALLEL MACHINE SCHEDULING WITH A SIMULTANEITY CONSTRAINT AND UNIT-LENGTH JOBS TO MINIMIZE THE MAKESPAN

LIN, LIN; LIN, YIXUN; ZHOU, XIANWEI; FU, RUYAN - In: Asia-Pacific Journal of Operational Research (APJOR) 27 (2010) 06, pp. 669-676

In this paper, we consider the parallel machine scheduling with a simultaneity constraint and unit-length jobs. The problem can be described as follows. There are given m parallel machines and a graph G, whose vertices represent jobs. Simultaneity constraint means that we can process a vertex...

A GRASP approach to transporter scheduling for ship assembly block operations management

Park, Changkyu; Seo, Junyong - In: European Journal of Industrial Engineering 7 (2013) 3, pp. 312-332

In this paper, we address the transporter scheduling problem of ship assembly block operations management, which can be transformed into parallel machine scheduling with sequence-dependent setup times and precedence constraints. The objective is to maximise the workload balance among...

Reducing food losses and carbon emission by using autonomous control – A simulation study of the intelligent container

Haass, Rasmus; Dittmer, Patrick; Veigt, Marius; … - In: International Journal of Production Economics 164 (2015) C, pp. 400-408

During the past decades bananas were imported to Europe in reefer vessels. Often, these vessels returned to Central America empty. This resulted in high carbon emissions and high costs. Therefore, importers switched to reefer containers which are shipped to Europe by liner cargo services....
