Single item inventory models; time- and event-averages approach

Bazsa, E.M.; Iseger, P. den - Erasmus University Rotterdam, Econometric Institute - 2002

This paper extends a fundamental result about single-item inventory systems. This approach allows more general performance measures, demand processes and order policies, and leads to easier analysis and implementation, than prior research. We obtain closed form expressions for the Laplace...

Alternate Samplingmethods for Estimating Multivariate Normal Probabilities

SÃ¡ndor, Z.; AndrÃ¡s, P. - Erasmus University Rotterdam, Econometric Institute - 2003

We study the performance of alternative sampling methods for estimating multivariate normal probabilities through the GHK simulator. The sampling methods are randomized versions of some quasi-Monte Carlo samples (Halton, Niederreiter, Niederreiter-Xing sequences and lattice points) and some...

A framework for response surface methodology for simulation optimization

Neddermeijer, H.G.; Oortmarssen, G.J. van; Piersma, N.; … - Erasmus University Rotterdam, Econometric Institute - 2000

We develop a framework for automated optimization of stochastic simulation models using Response Surface Methodology …. The framework is especially intended for simulation models where the calculation of the corresponding stochastic response … stochastic simulation models in a non-automated fashion. In scientific applications there is a clear need for a standardized …

Stochastic programming for multiple-leg network revenue management

Boer, S.V. de; Freling, R.; Piersma, N. - Erasmus University Rotterdam, Econometric Institute - 1999

Airline seat inventory control is a very profitable tool in the airline industry. Mathematical programming models provide booking limits or bid-prices for all itineraries and fare classes based on demand forecasts. But the actual revenue generated in the booking process fails to meet...

Comparison of response surface methodology and the Nelder and Mead simplex method for optimization in microsimulation models

Neddermeijer, H.G.; Piersma, N.; Oortmarssen, G.J. van; … - Erasmus University Rotterdam, Econometric Institute - 1999

Microsimulation models are increasingly used in the evaluation of cancer screening. Latent parameters of such models can be estimated by optimization of the goodness-of-fit. We compared the efficiency and accuracy of the Response Surface Methodology and the Nelder and Mead Simplex Method for...

A comparison of models for measurable deterioration: an application to coating on steel structures

Nicolai, R.P.; Dekker, R.; Noortwijk, J.M. van - Erasmus University Rotterdam, Econometric Institute - 2006

Steel structures like bridges, tanks and pylons are exposed to outdoor weathering conditions. In order to prevent them from corrosion they are protected by organic coating systems. This paper focuses on modelling the deterioration of the organic coating layer that protects steel structures from...
