Abstract: A method of processing tasks having at least one action server and at least one production server (SP) in which the action servers execute the control of the tasks in real time and in a direct and priority manner. This control is master and integrates all the changes of states that may have occurred on the internal elements of the system and on the external elements. The missing elements corresponding to these changes of state are classed into four categories: internal or external, deterministic or nondeterministic. For each of these categories a method of resolution is formulated at the level of the production server (SP). The system includes at least two data transmission buses: a ‘process’ bus (BP) linking the action servers and action terminals and desks (R1, R2, . . . ) as well as the production server (SP) and a video bus (BVDO) linking the production servers (SP), the production desks and terminals (P0, P1, . . . ) and the augmented reality server (SRA).
