With industrial systems growing more and more complex, we are led to take explicitly into account the time dimension. In the industrial dynamic systems field, we have to consider the time aspect in the multi-agents systems.To do so, we lay stress upon the "vowels" approach in order to study the time dimension within each of the MAS dimensions such approach reveals. The current methods and tools don't allow us to take the general time aspect into consideration in a MAS. Once analysed the consequences of the consideration of time in each of its aspects, we suggest a set of methods and tools likely to solve the problems which appear and to implement a multi-agents-driven time reasoning. Next, these propositions have to meet the concrete applications from the industrial environment.
