Abstract: The invention relates to a system and a method for evaluating the reputation of a given entity by a primary evaluation centre, comprising the following steps: reception at the primary evaluation centre of a request by an applicant transmitting a request for an evaluation of the reputation of the given entity, processing by the primary evaluation centre of the applicant's request in order to formulate a personalized evaluation of the reputation of the given entity according to processing rules dependent on the characteristics of the applicant known to the primary evaluation centre, and sending of an answer to its request by the primary evaluation centre, to the applicant.

Abstract: The invention concerns a method and a system for behavioral simulation of consumers in a virtual market (MV). It consists in: setting up (A) a consumer agent behavioral model (MCCj) for each consumer based on behavioral primitives (PCj,n) and setting up (B) a supplier agent behavioral model (MCFk) for each supplier based on behavioral primitives (PCk,n). The supplier behavioral primitives (PCk,n) enable to generate stimuli (Sk) or factual (Fr) variables addressed to each consumer agent behavioral model (MCCj) which deliver, from decisional variables (Dj,k) , dedicated decisional variables (DDj,k) in the context of the virtual market. The dedicated decisional variables (DDj,k) are represented (C) in the form of behavioral trends. The invention is applicable to all types of market research.
