La représentation de la confiance dans l'activité collective Application à la coordination de l'activité de chantier de construction

Abstract : Specificities of the construction sector generate uncertain cooperative work context. Especially, the building construction is an "on-site" production activity. Therefore numerous dysfunctions can appear during the activity. For example we underline possible problems due to the ground composition, to the bad weather conditions, or dysfunctions related to interactions between participants (e.g. material supply, workers interfaces...). Coordination of building construction depends on a subtle combination between explicit vs. implicit interactions, where organization takes various forms (i.e. hierarchic, adhocratic and transversal). Quality of the collective process is thus largely dependent on autonomy capability and responsibility sharing of each of the involved actors. Our hypothesis is that such a collective context is mainly based on the notion of trust. Indeed trust has the capability to reduce the perception of risk and to enable action in uncertain environments. Consequently, we suggest applying trust notion to the issue of design of cooperation support tools, towards a new vision of collective activity management based on trust representation. This Ph.D research introduces the notion of "trust in the good process of the activity". We suggest that this one is dependent on each dimension of collective construction activity: its progress, the actors involved in its execution, the resulting building works (and their construction difficulty), as well as required execution documents (i.e. plans, reports...). Our methodology consists firstly in identifying the various trust criterions that we validate through a first terrain survey. Secondly we establish a mathematical model aiming at evaluating trust level based on cooperation context information. Then the proposition suggests a prototype tool, called Bat'iTrust, implementing a multi-views service-based software architecture. Finally the validation is assessed through both surveys and an experimentation stage. These ones allow us to confront our results to experimental subjects representative of the construction domain.
