Nowadays, the healthcare sector is rapidly changing. Hospitals are facing limited budgets and high costs. The logistics activities of hospitals in France (stock management, delivery, etc.) represent one highest cost components. costs can be reduced through an optimized inventory management system. optimization strongly dependent on accuracy demand prediction medicines. Many factors influence th...

We present a mortality model where future stochastic changes in population-wide are driven by finite-state hierarchical Markov chain. A baseline an initial ‘Alive’ state is calculated as the average logarithm of observed rates. There several more states and jump to next leads change (typically, improvement) mortality. In order estimate parameters, we minimized weighted quadratic distance betwee...

The state-space representations of certain nonlinear autoregressive time series are general state Markov chains. The transitions of a general state Markov chain among regions in its state-space can be modeled with the transitions among states of a finite state Markov chain. Stability of the time series is then informed by the stationary distributions of the finite state Markov chain. This appro...
