For most computationally intractable problems there exists no heuristic which performs best on all instances. Usually …, a heuristic characterized as best will perform good on the majority of instances but leave a minority on which other … heuristics do better. In priority rule-based scheduling, attempts to remedy this have been made by combining simple priority …

This contribution presents two heuristic approaches for multi-level, single-machine lot sizing and scheduling. The … first one is a variant of a so-called randomized regret based heuristic which is assumed to be the fastest available method … shows that these two methods are complementary, i.e. the randomized regret based heuristic performs good in those cases in …

This contribution acquaints the reader with a model for multi-level single-machine proportional lot sizing and scheduling problems (PLSPs) that appear in the scope of short-term production planning. It is one of the first papers that deals with dynamic capacitated multi-level lot sizing and...

The car sequencing problem is to find feasible sequences of product variants requiring specific options while taking care of sequencing constraints. First, a branching scheme and constraint propagation algorithms for the computation of feasible sequences are provided. Second, an algorithm is...

Zur Lösung des Economic Lot Scheduling Problems (ELSP) finden sich in der Literatur drei Ansätze mit unterschiedlich einschränkenden Annahmen: - Ansatz des gemeinsamen Produktzyklus (Common-Cycle-Approach) - Ansatz der gemeinsamen Basisperiode (Basic-Period-Approach) - Ansatz der variierenden...
