Method for controlling discrete event systems

Method, implemented by a computer infrastructure, for controlling the sequential evolution of a resource of at least one discrete event system modelled by a machine having a plurality of states and at least one transition for implementing, when a predefined event occurs, a change of the current state of said resource from a first state to a second state of said plurality of states, said method comprising, in the event of a request to change the current state of said resource, the following steps:

• reading, in a memory of said computer infrastructure, a first computer object representing said resource of the discrete event system, said first computer object describing the current state of said resource and comprising a function intended to be executed automatically by said computer infrastructure in the event of a request to change the current state of said resource from the first state to the second state;
• executing said function associated with the required state transition from the first state to the second state;
• updating the current state of said first computer object and/or generating a second computer object to represent all or part of said resource, the new current state described by the first computer object and/or the new current state described by the second computer object being determined respectively by the result of the execution of said function associated with the required state transition;
• recording the first and/or second computer objects in said memory of said computer infrastructure.
