Matrix-analytic methods (MAM) were introduced by Professor Marcel Neuts and have been applied to a variety of stochastic models since. In order to provide a clear and deep …
We consider a two-echelon supply chain: a single retailer holds a finished goods inventory to meet an iid customer demand, and a single manufacturer produces the retailer's …

Collective I/O, such as that provided in MPI-IO, enables process collaboration among a group of processes for greater I/O parallelism. Its implementation involves file domain …
In this paper, we consider a queue where the inter-arrival times are correlated and, additionally, service times are also correlated with inter-arrival times. We show that the …
We consider a supply chain in which orders and lead times are linked endogenously, as opposed to assuming lead times are exogenous. This assumption is relevant when a …
Les chaînes de Markov sont des modèles probabilistes utilisés dans des domaines variés comme la logistique, l'informatique, la fiabilité, les télécommunications, ou encore la …
This paper considers a discrete time, single item production/inventory system with random period demands. Inventory levels are reviewed periodically and managed using a base …

Using Erlangization, we construct two types of continuous phase-type (PH) random variables that approximate discrete PH-random variables and finite discrete random …
Acyclic phase-type distributions are phase-type distributions with triangular matrix representations. They constitute a versatile modelling tool, since they (1) can serve as …
