Gruppierungs- und Reihenfolgeprobleme der Fertigung zählen zu den zentralen Fragestellungen der (operativen) Produktionsplanung. Gruppierung bezeichnet dabei die zu treffenden Entscheidungen über Größe und zeitliche Lage von Fertigungsaufträgen (Losen), während der Reihenfolgeaspekt die...

Das zunehmende Interesse an der Analyse dynamischer Prozesse und die sich ständig verbessernde Verfügbarkeit der zu ihrer Untersuchung notwenigen Datensätze lassen die Frage nach geeigneten Verfahren aufkommen. Traditionelle Methoden wie logistische und lineare Regression sind entweder nicht...

This paper addresses an airport gate assignment problem with multiple objectives. The objectives are to minimize the number of ungated flights and the total passenger walking distances or connection times as well as to maximize the total gate assignment preferences. The problem examined is an...

We build a two-country dynamic general equilibrium model to study whether European citizens would benefit from the eventual accession of Turkey to the European Union. The results of the simulations show that Turkey's accession to the European Union is welfare enhancing for Europeans, provided...

We introduce a network formation model based on the idea that individuals engage in production (or decide to participate in an action) depending on the similar actions of the people they observe in the society. We differentiate from the classical models of participation by letting individuals to...

This paper is concerned with modelling time series by single hidden layer feedforward neural network models. A coherent modelling strategy based on statistical inference is presented. Variable selection is carried out using existing techniques. The problem of selecting the number of hidden units...

A general equilibrium model is built to explain if there are circumstances in which exchange rate risk smoothing (ERRS) policies may bring a Pareto-improvement for a indebted small open (home) economy. The model shows that this is the case when overpessimistic foreign creditors demand a large...

In this paper, the Local Global Neural Networks model is proposed within the context of time series models. This formulation encompasses some already existing nonlinear models and also admits the Mixture of Experts approach. We place emphasis on the linear expert case and extensively discuss the...
