In most multi-item inventory systems, the ordering costs consist of a major cost and a minor cost for each item … included. Applying for every individual item a cyclic inventory policy, where the cycle length is a multiple of some basic … discussed in this paper. It is shown that this algorithm can be used for deterministic multi-item inventory problems, with …

In this paper an inventory model with several demand classes, prioritised according to importance, is analysed. We … consider a lot-for-lot or (S-1,S) inventory model with lost sales.For each demand class there is a critical stock level at and …

In this paper we analyse the effect of a cutoff transaction size in a simple newsboy setting. It is assumed that customers with an order larger than a prespecified size are satisfied in an alternative way, against additional cost. For compound Poisson demand with discrete order sizes, we show...

We propose a new methodology for designing flexible proposal densities for the joint posterior density of parameters and states in a nonlinear non-Gaussian state space model. We show that a highly efficient Bayesian procedure emerges when these proposal densities are used in an independent...

We propose a new Markov switching model with time varying probabilities for the transitions. The novelty of our model is that the transition probabilities evolve over time by means of an observation driven model. The innovation of the time varying probability is generated by the score of the...

In this paper we investigate whether the dynamic properties of the U.S. business cycle have changed in the last fifty years. For this purpose we develop a flexible business cycle indicator that is constructed from a moderate set of macroeconomic time series. The coincident economic indicator is...

In this paper we replace the Gaussian errors in the standard Gaussian, linear state space model with stochastic volatility processes. This is called a GSSF-SV model. We show that conventional MCMC algorithms for this type of model are ineffective, but that this problem can be removed by...

We investigate high-frequency volatility models for analyzing intra-day tick by tick stock price changes using Bayesian estimation procedures. Our key interest is the extraction of intra-day volatility patterns from high-frequency integer price changes. We account for the discrete nature of the...
