This paper deals with system support for the design of CSCW environments. Our model introduces objects spaces shared by cooperating participants and cooperation spaces which group participants involved in a particular cooperation together. Objects spaces are only accessed via cooperation spaces. This makes our model strongly cooperation oriented. The Group notion structures our system, called O...

Philippe BAPTISTE

Air-traffic management (ATM) consists of a predictive component (traffic planning) and an adaptive component (traffic control). The aim of the predictive component is to balance airspace demand with available capacity. The adaptive component has to guide aircraft safely to their destinations, once they are in the air. Uncertainties (e.g delay from connecting flights, technical failure) create t...

SBGM: Conciliation et mesures de conflits

We propose to define new conciliation operators. Those operators are based on an iterative selection/weakening process of the beliefs/goals of the agents, until a consensus (agreement) is found between the agents. To define a particular operator, it just need to choose a choice function and a weakening function. In previous works the choice function was defined arbitrarily. We propose to take a...

Analytic Urns Philippe Flajolet

The talk1 describes an analytic approach to urn models of the Pólya type where an urn may contain balls of either of two colours. At each step, a ball is randomly drawn and replaced by balls of the two colours; a fixed 2× 2-matrix with constant row sum determines the replacement policy. The treatment starts from a partial differential equation associated with the model and bases itself on confo...
