Finding maximum likelihood parameter values for Finite Mixture Model (FMM) is often done with the Expectation Maximization (EM) algorithm. However the choice...

<p>The well-known method stochastic programming in extensive form is used on the large scale, partial equilibrium, technology rich global 15-region TIMES Int...

We consider an inventory routing problem in discrete time where a supplier has to serve a set of customers over a time horizon. A capacity constraint for th...

We study the convergence behavior of a randomized quasi-Monte Carlo (RQMC) method for the simulation of discrete-time Markov chains, known as array-RQMC. The...

We consider a class of Markov chain models that includes the highly reliable Markovian systems (HRMS) often used to represent the evolution of multicomponent...

A profit and a demand are associated with each arc of a set of profitable arcs of a given graph. A travel time is associated with each arc of the graph. A fl...

This paper studies sustainability from both an economic and environmental perspective. We concentrate in two separate but interlinked environmental issues: t...

The Dutch railway network experiences about three large disruptions per day on average. In this paper, we present an algorithm to reschedule the crews when s...

<p> The complementarity of two renewable energy sources, namely hydro and wind, is investigated. We consider the diversification effect of wind power to re...

A recent paper of Tuy and Hoai-Phuong published in <i>JOGO</i> (2007) 37:557--569 observes that there are errors in the reformulation of a signomial geometr...

In this article, we consider nonparametric regression analysis between two variables when data are sampled through a complex survey. While nonparametric regr...

In this article, we introduce a class of multivariate seasonal time series models with periodically varying parameters, abbreviated by the acronym SPVAR. The...

The <i>Generalized Vehicle Routing Problem</i> (GVRP) is an extension of the classical <i>Vehicle Routing Problem</i> (VRP) in which the vertex set is partit...

This paper deals with the class of continuous-time singular uncertain linear systems with time-varying delay in the state vector. The uncertainties we are co...

It is now accepted that climate change is due to the cumulative and joint effect of multiple atmospheric trace constituents. The importance of adopting a com...

Tree based methods have not yet been adapted to handle mixed effects. Previous works extending them to accommodate correlated data are based on the multivari...

Should manufacturers of durable products such as automobiles and household appliances offer cash rebates to all consumers at the time of purchase, or offer t...

A magnet is a pair <i>u,v</i> of adjacent vertices such that the proper neighbours of <i>u</i> are completely linked to the proper neighbours of <i>v</i>. It...

This work proposes a statistical methodology to handle aggregate data. Aggregate data arises in many fields such as medical science, ecology, social science,...

This research assesses the impact of the various states of mind of Flow psychological theory (Csíkszentmihályi 1990) in relation to brand recall and recognit...
