The problem of scheduling multiple, large scale, make-to-order assemblies is considered. Beside "classical" precedence- and resource constraints as known from resource constrained project scheduling we take spatial resource and part availability constraints into account. The objective is to...

We consider the problem of scheduling multiple, large-scale, make-to-order assemblies under resource, assembly area, and part availability constraints. Such problems typically occur in the assembly of high volume, discrete make-to-order products. Based on a list scheduling procedure which has...

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...

Purpose: The purpose of this research is to develop an optimization model of CNC turning process. The objective function of the model is to minimize processing time and carbon emission. We implemented the results of optimization with real machining application using a certain workpiece....

A flow line consists of a sequence of work places (or stations) through which one or more producta (or models) move one-way in order to be processed. Each model requires specific Operations which must be performed in a predefined Order. To be able to do so, the stations must be equipped with...

This paper presents a mixed-integer program for the dynamic lot sizing and scheduling problem in a multi-level, single-machine environment. It turns out that in contrast to single-level problems the integration of initial inventory is a crucial aspect if generality should not be lost. It is...
