Level Scheduling, which aims at distributing the part consumption induced by the model sequence evenly over time …. Traditional Level Scheduling seeks to closely approximate target demand rates at every production cycle, however, such a strict … consumption pattern between two delivery points seems irrelevant. The paper on hand provides new Level Scheduling models, proves …

Solving symmetric mixed-model multileveljust-in-time scheduling problems

Fliedner, Malte; Boysen, Nils; Scholl, Armin - Universität <Jena> / Wirtschaftswissenschaftliche Fakultät - 2008

The generation of leveled production schedules is of high impor-tance for mixed-model assembly lines whose parts and materials are suppliedjust-in-time by multi-level production processes. The Output Rate Variatonproblem is the standard mathematical representation of this complex levelscheduling...

Scheduling freight trains inrail-rail transshipment yards

Boysen, Nils; Pesch, Erwin - Universität <Jena> / Wirtschaftswissenschaftliche Fakultät - 2008

Transshipment yards, where gantry cranes allow for an ecient transshipment of containersbetween different freight trains, are important entities in modern railway systems andfacilitate the general shift from point-to-point transport to hub-and-spoke railway systems.Modern rail-rail transshipment...

Scheduling Aircraft Landings toBalance Workload of Ground Staff

Fliedner, Malte; Boysen, Nils - Universität <Jena> / Wirtschaftswissenschaftliche Fakultät - 2008

Scheduling landings of aircrafts is an essential problem which is continuouslysolved as part of the daily operations of an airport control tower. All planesin the airspace of an airport are to be assigned to landing slots by the respon-sible air-trac controller. The support of this decision...

Managing and modelling generalresource transfersin (multi-)project scheduling

Krüger, Doreen; Scholl, Armin - Universität <Jena> / Wirtschaftswissenschaftliche Fakultät - 2008

Most approaches to multi-project scheduling are based on the assumption that resources can betransferred between projects without any expense in time and cost. As this assumption often isnot realistic, we generalise the multi-project scheduling problem (RCMPSP) by additionallyincluding transfer...

Scheduling Inbound and OutboundTrucks at Cross Docking Terminals

Fliedner, Malte; Boysen, Nils; Scholl, Armin - Universität <Jena> / Wirtschaftswissenschaftliche Fakultät - 2007

At cross docking terminals, shipments from inbound trucks are unloaded,sorted and moved to dispatch points where they are directly loaded onto out-bound trucks for an immediate delivery elsewhere in the distribution system.This warehouse management concept aims at realizing economies in...

A heuristic solution framework for theresource constrained multi-projectscheduling problem withsequence-dependent transfer times

Krüger, Doreen; Scholl, Armin - Universität <Jena> / Wirtschaftswissenschaftliche Fakultät - 2007

We consider the problem of scheduling multiple projects subject to joint resource constraints.All approaches proposed in the literature so far are based on the assumption that resources canbe transferred from one project to the other without any expense in time or cost. In many realworldsettings...
