This research concerning the North Atlantic Ocean is trying to establish a link between the extreme hurricanes (categories 4 and 5) activity and the global warming over the period 1945-2018. The hurricanes intensity has been estimated from 1945 to 1977 with the aircraft reconnaissances. These data come from the Hurdat database of National Hurricane...
This research concerning the South Pacific Ocean shows the 10-year and interannual variability of extreme cyclones (categories 4 and 5). The intensity of these cyclones has been reanalysed on the basis of GMS, GOES and NOAA satellite images with the Dvorak technique. In the period 1980–2016, 63 cyclones reached categories 4 and 5. During the decade...
This paper tries to analyze and evaluate emergent structures in a multi-agent system which is able to resolve the warehouse location problem. These emergent structures allow agents to optimize their planning time and to improve their adaptive behavior in an unknown environment. In our multi-agent system, each agent is based on an on-line building a...
We focus on the problem of strategic network design in the context of multi-site enterprises. We develop a simulation model for various supply network designs evaluation. The suggested model is generic in the sense that only input data modifications are needed to adapt the model to a given supply network structure, while the model's procedural logi...
Mathematical programming approaches, like linear programming (LP) or mix-integer programming (MIP) are widely used as an optimization tool, since they can compute the best possible configuration of a constrained system. However, the needed computing resources and time cannot always be figured out in advance, and happen to be beyond available resour...
In this paper, we describe a generic scalable simulation model for the redesign of the supply chain of multi-site enterprises. Our model makes it possible to reproduce the dynamic of the supply chain and the information and material flows between its various entities. In particular, we concentrate on the modelling of the activities which take place...
Numerous authors have identified discrete-event simulation as an effective tool for evaluating the performances of complex systems’ control policies prior to their implementation. Simulation permits decision makers to perform powerful what-if analyses leading them to understand correctly the system, to build appropriate decisions, and to compare va...
