We propose a new method to obtain bounds of dependability, performance or performability measures concerning complex systems modeled by a large Markov model. Its extends previous published techniques mainly designed to the analysis of dependability measures only, and working under more restrictive conditions. Our approach allows to obtain tight bounds of(More)
his paper deals with the design of modelling tools suitable for investigating the consequences of alternative policies on the dynamics of resources and fisheries, such as the evaluation of marine protected areas (MPA). We first review the numerous models that have been developed for this purpose, and compare them from several standpoints: population(More)
Ecosystems are usually complex, nonlinear and strongly influenced by poorly known environmental variables. Among these systems, marine ecosystems have high uncertainties: marine populations in general are known to exhibit large levels of natural variability and the intensity of fishing efforts can change rapidly. These uncertainties are a source of risks(More)
A length-structured spatially explicit model for estimating hake growth and migration rates. – ICES Journal of Marine Science, 67: 000– 000. Despite an abundant literature, hake growth and migration remain poorly understood. A recent tagging campaign and an analysis of the growth increments on juvenile hake otoliths demonstrate that the growth rate has(More)
